I installed my engine on port side for the third time. First time happened when a lack of maintenance on the engines from a previous owner led to a broken spark plug. NIGHTMARE. Pulled the heads and all of the spacers came off with it in order to easy out or heli coil the head. Long of the short - had a mechanic so he says he was one rebuild it. NOT CHECKING FOR VALVE CLEARANCE AFTER SETTING THE TIMING- Used the STARTER BUTTON! BOOM ? (engine number 1)
Engine 2 - SBT MOTOR, 1 year warranty. Leaked from the valve cover as soon as I transferred all the parts over. SBT sent me a new valve cover gasket, I changed it out. Got another 2 uses out of the boat and same engine BOOM ? - under warranty SBT swapped my motor. They got
It back and that was that. New motor OTW
Engine 3 - stripped the engine out. Used the manual , torqued it all down in my buddies shop. Used the proper lock tight, transferred everything all good ! According to the Yamaha manual. Triple checked it. I just took my boat out. Oil return hose from the cooler to the air box blew off. Oil dripping , checked the level , resecured it. Kept it moving. At 8500-9000 peak rpms. Went another 10 minutes toward the Statue of Liberty and BOOM ? engine shuts down and blew all
The oil out of the valve cover gasket side half moons opposite of the oil cooler side. I shove them back into place , fill it up with oil. Spun the key. Fires up , and I go another 2 mins watching the valve cover gasket. 5000 rpm , blows out - shut it down. Plug the intake and I start the miserable ride of motoring home on one motor. WHAT IN THE **** Can I check to solve this problem. SBT says might be oil pressure is too high( I don’t disagree - it blew out the valve cover gasket) , a respectable mechanic brought up blow by (I agree as well) as a for sure problem. What should
My oil pressure be in a non HO MR1 and will the oil catch can solve my problem or just band aid it. Is is possible that my oil pump bearings are letting oil escape ? What are my options here and what should
I look at. I’m in the boat deep already as you all can see. At this point I want the thing to be fixed and when I figure out what boat I can write off in NJ. That’s the boat I’ll buy. I’m too far committed into this boat to back out of it. (Speakers, ELECTONICS, wrap , lights , interior)
