I have a 2001 Prostar 190 - LTR 330hp (duvall) 395 hours – 60 this year
My boat is not sounding or running well at all. Here are the symptoms:
I have a severe loss of power. - At 3000 rpm, I run at 24mph.
At full throttle I only get 4000 rpm and a sad 34mph
With me skiing (just once, the first time I noticed problems) the boat topped out at 31mph
Oil pressure sits at 20-40 always, and at idle bounces to 0 for short milliseconds
Temp gauge never makes it to 120. The faster I run, the cooler it gets, down to 90deg
(the engine and exhaust manifold are never hot to the touch)
After running fast for a minute or two, there is a ticking which I can not locate, and lasts until the engine is shut down.
The engine has a slight vibration at about 1500rpm
Gas seems to disappear quicker than normal, although that may be my own misjudgment.
My sister, to avoid chewing me up, had to use a generous amount of reverse (Last week before I noticed any problems), and a fair (not too much) amount of dark smoke came out the exhaust. I’m thinking that this is not related or too much of a big deal
This all seems to have just happened in the past week. I have been out skiing almost every day until now. I took a week off due to t-storms and now its running bad. If I think hard, it is possible that the performance did drop a bit in the recent past, as I noticed a few times that my faster skiing friends made the boat work a little harder than usual. But no symptoms even close to this extent.
Background:
I float the boat 24/7 in a muddy river with 3mph of current. It has been in since May 1st. I pulled it out, cleaned the outside, and took it to another (much cleaner) lake once for July 4th weekend. There is definitely a lot of mud/algae that forms on the bottom (and maybe in the cooling system)
Another thing, before I went out today, when I put the boat in gear for the first time, I chopped a small stick that must have been under the boat (very soft, about 1”dia). So maybe this has something to do with that.
SO,
My (un-educated) thoughts are, the boat is having fuel problems, running WAY too rich, which is causing the low temperatures and lousy performance, and fouled out a plug which causes the ticking. – this is most definitely way off, which is why I bring this to all of your incredible wisdom. I really don’t think it is a prop problem, I have hit stumps in other MCs before and know what a bent prop feels like. I felt under the boat with my feet (there is no visibility under water) and the prop & rudder feel fine. Also, although it may cause the lack of speed, the rpm would still run higher like it did before right?
Also, how do I check the cooling system for operation while the boat is in the water?
Thanks for the help!
