1997 Complete Renovation of Prostar 190 with Steyr 236 Diesel Engine

**kiteklan** · 12-30-2009, 10:15 AM

Diesel Engine and some accessories

4200 RPM 236 Horse Power Steyr 236 Engine 380 kg with the transmission
I have one propeller right now with a diameter 36cm but I guess it will not be enough,my plan is to lunch the boat with this propeller and get the draft and waterline with the engine,I have no idea about its draft and waterline and the total weight that is why ordering a propeller will not be wise without a certain measurement.

I about the trailer ,rims are from one of my old car (1989 Probe GT),I will try to get it lower and adjust the axels to the center of weight when I will finish the boat.
It is not easy to this work in Turkey since original parts are not easy to find and expensive.

Platform after some work

Insturment Panel

Instrument Panel,

Original panel was in very bad condition ,we had covered it Fiberglass and make new holes for guages.

I was thinking to use Volkswagen Marine 225 V6 but it was above my budget.Steyr 236 is a light weight and powerfull engine but its dimensions are bigger then orginal mastercraft engines.

Does anyone has an idea how much an orignal mastercraft engine weighs(total weight with transmission? and RPM ,Transmission ratio?

There are more pictures on the my website

Looking Good.

I am really interested in how that diesel performs in the boat.

Definitely making progress. Keep up the good work!

thanks ,I am trying to finish it in 2 weeks.

The motor should weigh 227-272 kilograms fully dressed. A transmission was likely originally a hurth 1:1 and would have weighed probably in the neighborhood of 68 kilos. Operating RPM range would have been about 600rpm to a max of 4600-5000rpm. These are just rough figures, nothing exact. maybe someone else can help out with exact numbers.

awesome project

Just a guess... but I think you will be disappointed with the boats performance if you go to all the trouble of making that engine combination fit. It looks like it is only a four cylinder engine in the photo.

I disagree to some extent.......diesels do take longer to "spool up" so the 0-36 mph time will suffer, but it should "hold" speed rather well (good for slalom), get 2-3 times the fuel economy of a gas V-8 and last much longer too. It would be a great engine choice in a wakeboard boat (heavy, ballast). I know diesel is the way to go for alot of reasons in europe.

Did you consider a 5.7 liter V-8 powered by propane? I know that's a good combo in europe as well.

BTW, that gelcoat is looking good!

2-week project? That's awesome! Looking forward to the pics as things progress.

Carpe Diem!

Thats also a rather high RPM diesel, so perhaps the spool up time will be lessened somewhat.

On the positive side, diesels have tremendous low end torque so that may have some hole shot assistance.

Can't say anything before finding the exaxt prop and testing it in the sea
Transmission ratio is 2:1 which is not good that is I know but I will try to find a big prop with a high pitch.Other then that the engine is a 6 cylinder 3.2 liter gives max 440 Nm Tork at 3300 Rpm.
I atttached the engine data in Pdf.

440 NM = 324.48 Lb/Ft is what this engine produces.

RTP engine 310 HP 360 ft.lb. (488NM)
MCX engine 350 HP 380 ft.lb.(515NM)
VW TDI 225HP 335 lb (454NM)
1 foot-pound is closely equivalent to:1.3558179483314 newton meters

I think in respect to fuel economy and performance ,overall we will get a 4/5.

Thanks for the comments.

Nj,It took about 2 months to find this engine,those engines are not still show up in the 2nd hand market,this engine was at 600hr and year 2002 that is why we chose it.
For the progress check the pictures

.

Name Stickers were for registration,we will work on something look nice with decals .
