OK, been having a rough start to the summer with my boat! So I had to change my Carbon seal, no problem, changes the carbon ring, 2 rubber seals and the snap ring. I purchase 2 ring clamps from Canadian tire to replace the factory one on the front boat by the grease nipple. I then pump some grease in the the nipple. Water test, all good, no more leaks from the carbon seal.
I still have a bit of an engine stutter in the mid range, but only after the engine warms up. I am going to change the fuel filter since I have never done this and get the TPS checked and aligned.
Yesterday afternoon, I was getting on plane with close to full throttle, all of a sudden this vibration immediately started. very consistent vibration through the rpm range, feels like something came out of balance.
So I cruise back, take it out of the water, inspect the pump, nothing. Take the pump off, nothing. Start it with the pump out, still vibrates.
Could this be a motor mount? If a counter balance in the crank failed, the engine wouldn't rev to top rpm as correct? And if the counter balance shaft failed, I am sure it would result in a destroyed engine correct? I also see we should be changing the oil in the counter balance shaft. I have never done this the 3 years I have owned this boat. The engine was a new crate engine from BRP in 2011.
Motor mounts are hard to see but I will recheck those after work today.
I did notice grease I put in the nipple on the flywheel, a lot dissipated out into the engine bay (messy now)
Could that be related?
Any ideas?
