    "Who wants a Moustache ride?"

    Comment

      Fuel gauge is the sender unit. Replace it.

      Transmission fluid is Tech(brand) Mercon. You can get it online. It supports Mercon 3-5 in Ford engines, and I swear by it now.

      Decals for your boat are $80.00, and you can order them directly from Mastercraft. They look freaking awesome new.

      Also, if you can, run it for a few hours, and get an oil sample. This will give you a good idea about engine conditon.

      Hope I answered all of your questions, as far as trailers, I had one built.

      Message me, and we can exchange numbers. I did this restoration last year, have 20 hours on the boat, and no issues.

      Best regards,

      James.

If it was a highly stressed, high speed, automotive engine running in the desert at 100 degrees the 20w-50 would be OK, but IMO there's no need to use anything other than a 10w-40. I use Rotella 15w-40 because of recommendations on this forum, and it's also cheaper than others when you buy it by the gallon. (on sale for typically $12)

        I bought some Rotella Synthetic 5w-40 on sale for $12/gal, so that's what is going in next time.

        Almost any quality oil will work great as long as it's changed regularly and you don't let it sit all winter.

        YMMV
        I'm using the factory recommended 10 / 30 in mine. You need to change oil every 50 hours, and every 100 hours full oil change, filter, etc.

          Thanks--I've never used a boom before, so I appreciate the comments. The handle part of the boom does have a bend just before it inserts into the part that attaches to the pylon. It didn't seem unusual, but I'll take a close look to make sure that's the way it should be and it is not bent.
          It is common to have the section of the boom mounted to the pylon bent. This is referred to as a contoured boom, meant to allow the user to mount the boom (and pylon bracket) closer to the floor. I have never seen the outside piece bent from the manufacturer.

          I’m not an expert. Just double check. A boom failure at best will cause damage to the boat, as the cables are unlikely to release. At worst, it causes significant injury to the skier. Great tool for teaching.

          Great find with the boat by the way.

            That boom is bunk.

            A contoured boom is a second generation boom design (1st gen - straight boom) to allow the boom to clear the extended length of the windshield onto the gunnel (beyond the parallel location of the pylon as was the 1st gen).

            Further, a height extender on the pylon or manual adjustment on the pylon allows for up and and down height adjustments for smaller or taller skiers.

            Each to their own.

                Thanks for all the comments! Please keep the feedback coming.

                Last night I finally had some time to start working on the boat. New roller went on the trailer, cut some treated plywood slabs to protect my asphalt driveway, got the drain plug out (easily!) after a 24 hour soak with PB Blaster, and lubed the latch on the trailer.



                Took a closer look at the bend in the end piece of the boom. I don't see any cracks near the bend. Guessing it is still not a good idea to use it, is that right?


                Spent some time eyeballing the drive line after reading some threads here about dealing with vibrations. The boat has a minor vibration when getting up to speed. Nothing when idling in gear or at speed. Looks like the cutlass bearing needs to be replaced, and at the very least, I need to do an alignment. Since it is lake season, I'm thinking I'll try to align it now so I can get on the water, and order the bearing now so that I can take on that job when I have more time. Given the way the drive shaft rides in the cutlass bearing and the side to which the drive shaft goes through the hole in the hull, I'm hoping that I'll be able to get it aligned, but I am a bit concerned that the strut may be bent. To my untrained eye it looks straight, but the way the drive shaft is wearing the cutlass bearing on the port side in front and starboard at the back makes me concerned. Thoughts?






                I've got new trans fluid, Rotella T4 15-40 and a Motorcraft filter ready to go. Package from SKIDIM arriving today with two new pitot tubes, a tube of 5200, and the fuel tank sender arrives today. Still need to pick up a fiberglass repair kit for the muffler and a spare tire.

                  Another thing--the strainer only has two screws holding it on--there are four holes in it. Is looks like there are no empty holes in the hull though. Is that typical? The caulk around the strainer is also not in good shape. Since I have the tube of 5200 for the pitot tube replacement I'm tempted to pull off the strainer, clean up the hull, and reinstall it.

                    Updates!

                    UPDATE! I've been chipping away at my to do list on the ProStar. Happy with the progress, but still more to do! I've really enjoyed it so far. (Bought with 741 hours, rolled over 750 hours with this past weekend)

                    New fuel sender went in to fix the inop gas guage. New and old:


                    Pulled the muffler, ground out around the leaks which were all where the tubes met the body, and then glassed over the joints. Once cured, I painted it with engine paint. Finally, a few layers of plumbers tape on the threads of the drain plug. Looks great and no more leaks!


                    Help is important...


                    Ready for paint.


                    Back in. Here you can also see the new bilge vent hose.


                    New pitot tubes. These replacements from SkiDim have three holes vs the two of the OEM ones. I drilled out the bottom two holes to match up to the holes in the boat, and had to cut the top mounting hole off of the new pieces to fit under where the hose comes out of the boat. Mounted with 3M 4200 and two screws.


                    The hoses were original and showing cracks, so I replaced them all. I used a miter saw with a metal cutting blade to cut them to size. Makes a cloud of awful smoke, but makes a decent cut of the hose and wire embedded within. If you use this cutting method, make sure to wear a mask! Don't want to breathe that smoke...
                    Naked!

                    New hoses installed. Bought from SkiDim by the foot, and cut to size. The pre-formed hose needed to be trimmed, as SkiDim advised, to fit.


                    New trans fluid. Old stuff smelled fine. It was dirty, but not terrible.


                    New wheels and tires were a must. Old tires had a manufactured date of 2001, and when we head to the cabin its a 250 mile round trip. Thanks to @ThatsMrMastercraft for the help with wheels and tires. This pic also shows what a wash and wax can do. I used Meguiar's Gold Class Car Wash Shampoo & Conditioner, and Meguiar's Synthetic X-Press Spray Wax. Not much work, but made it look like a new boat. Also treated the vinyl with 303.


                    Stuff I didn't take pictures of:
                    -Greased the trailer bearings
                    -Replaced the shaft packing with GFO
                    -New impeller
                    -Oil change with Rotella 15-40
                    -Tightened pylon--it was loose!
                    -Greased rudder and steering
                    -New MasterCraft decals on the side--probably going to redo them. I'd like a slightly grey color, and want all of the side and back decals to match.


                    Still on my To Do List:
                    -Replace alternator belt (should have done this when I did the hoses)
                    -Shampoo carpet
                    -Replace wheel bearings -- they didn't get hot on the highway, but age and history is unknown. Better safe than sorry.
                    -Replace cutlass bearing
                    -Restore teak platform
                    -Ski, ski, ski!

                        where about are you in WI?

                        take a picture of the strut from straight on from the back.. make sure it is not bent...usually that is what makes that happen...

                        looks good!

                        If there is nothing wrong with the bearings I would just plan on repacking every 2 years and leave it at that...

                            I live on the west side of Milwaukee, and we have a cabin in Waupaca, on Spencer Lake.

                            I'll try to get a decent pic of the strut from behind. Thanks!

                              More progress!

                              After spending more time eyeballing the strut, I realized that the strut on the boat was in fact bent. I removed the old strut, which was a pretty easy process. I did not pull the drive shaft, just removed the bolts on the coupler and let it be free. With a bit of heat and hand pressure the strut came right off. The remaining caulk / sealant on the hull came off with Goof Off Pro and a plastic scraper. I dry fit the new strut (purchased from MCPartsDepot.com) and the drive shaft was almost perfectly centered in the shaft log, so I went ahead and installed it, using 3m 4200. The new strut comes with a new bushing already installed. The process of aligning the drive is an art, not a science... Adjust, measure. Adjust, measure. Tighten motor mounts, remeasure, curse, repeat process. My last time through it was getting late and was around .006 after tightening down so I called it good. Going to revisit this again to see if I to get it to .003 or better.



                              Still had the vibration, so the next step is the prop. I considered just having the old prop rebuilt, but the idea of getting a modern four blade CNC machined prop was too enticing. I went with an OJ 454, purchased direct from OJ and they are going to rebuild the old prop, after which it will be a spare.



                              Last night the boat was smooth as can be for the first time since I've owned it. I wouldn't say the prop made it a new boat, but it did improve the hole shot and add about 2 mph to the top end. I also think it made the wake where I ski at 15' off a bit smoother. I also got my six year old son up on skis behind the boat for the first time, which was fantastic! He has also been practicing his boat driving.



                              I have boiled linseed oil and mineral spirits on the shelf in the garage for when I have time to tackle refinishing the platform.

                              Good stuff, loving the boat!

                                I thought those 351's were supposed to run that valvoline oil with some additive for the flat tappet cam. Did something change along the way?
