Blown Pro-V

[fisherd]

I have a 1997 200 Pro V, it has one blown cylinder but everything else seems to be ok. Can any one give me an idea on what it is worth as is?

They are the best in the nation. They replaced the head on my HPDI, I wouldn't let anyone else touch it.

Ask for Nathan or Jon they'll give you strait answerer's and while your at it if your not familiar with there phase kit you better check on them.

Hey, how about that, my 97 Pro V 200 just blew one too. Really interested in your replies. Gonna be costly no matter what I'm sure, to fix that is.

So, what caused your engines to let go?

Thanks!

Not if you get a good shop manual and do it yourself. I'm rebuilding mine for the first time.

No idea, run it regularly, use ring free, stabil- seems like no matter how well you take care of them, they just don't last as long as what they cost!

Thanks for replying and good luck to you!

I have a V-Max 225 OX66 fuel injected and also blew the engine on Nov. 3rd. 2007 but not really the whole engine just the piston in cylinder #3 came apart, sound familar to any one? I took it to Reynolds Performance Marine in Shepherdsville Kentucky just 25 minutes south of Louisville. Tony, the owner, spent over 5 hours with me and took the engine apart enough to inspect it and determined it was rebuildable. What I couldn't get from anyone else is what caused the failure, I sure didn't want to go through this again. What he determined with my help and a little history on the engine is back in early April I had problems with the engine running poorly during a fishing trip to Cherokee Lake in Tennessee. This thing was going through gas like there was no tomorrow. I took it to a Yamaha dealer and they said that two of the three fuel pumps had bad diaphrams, one totally destroyed and the other partially cracked, they replaced all three and saved my vacation. As it turns out the pump that totally failed was dumping raw, un-oiled fuel directly into the #3 cylinder washing away any lubrication. Not enough damage at the time to destroy the piston but after 6 more months of running it took it's toll, piston three began to come apart at 3500 rpm. Bottom line is when these fuel pumps fail they dump raw fuel into the particular cylinder that drives the pump. The crankcase is partitioned off with basically a mini crankcase per cylinder, thats why in my situation just one cylinder failed. I'm sure the cylinder that was running the second failing fuel pump wasn't too far behind.

Estimates were $5000- to $6200 with Reynolds being the lowest to rebuild the existing engine. Reynolds also offered the best warranty, 365 days only while using the boat, have hin winterize it in the fall and and he stops the warranty clock until you have him de-winterize it basically giving you two seasons of warranty.


Call Tony at 502-543-6774 or go to the Kentucky Boat Show in Louisville Jan 26 thru Feb. 3rd. to see his booth full of completely rebuilt engines

He is currently in the rebuild process. I told him I didn't need it until the last week of March. It's a 2001 OX66 and not an HPDI model just fuel injected.

The rebuild will include new pistons, bearings, 1 head, reed valves, gaskets, and fuel injectors sent to an injector shop in Louisville to be ultrasonicly cleaned & tested, any that don't meet specifications when tested will be replaced.

Before I pick up the boat he will have run the engine for 3.5 to 4 hours to make sure it's properly broke in. He takes pictures as he goes and makes a DVD to help you remember what you need to be doing after the rebuild to complete the process and keep it running good.

I could be wrong, but I always thought the fuel for the three lp pumps came from the VST where the fuel and oil were mixed. The lp pump diaphragm failure would cause the pump to dump excessive amount of oil/fuel mix--not just raw fuel......

[skeeter150]

Your reply brings up a question I have. is it possible to pre mix the oil and gas as many people do for smaller motors and would this prevent such accidents?

[skeeter150]

hey isle of palms- what would you estimate one cylinder fix to run???

[wayniac]

From what I saw those three pumps job is to bring fuel up to the engine from the fuel tank/s to the VST where fuel and oil are then mixed. The inside of the crankcase is seperated into a section for each cylinder by what looks like huge piston rings on the crank making 6 seperate crankcases, only three of the crankcase sections are used for the puel pump operation. The pump operates on normal presure fluctuations in the crankcase, one crankcase section for each pump, thats how I only had one cylinder fail.
