I have been trying to resolve an issue were my Motor appears to run fine on muffs and in a barrel, but when I take it to the lake it falls on its face trying to accelerate above "No Wake" Speed. (Not sure of the Exact RPMs) I have been trying to resolve this in the Ignition System yet everything is checking out appears to be within range.
It has been indicated that I am probably loosing "Crankcase Pressure" when the boat is under a load and that I probably need to replace the Lower Main Seal.
Is there any practical way to test "Crankcase Pressure" before having to tear the motor down and hope to see an obvious issue?
I have squirted the engine with a Soapy solution and did not see any bobbles forming, from the visible surfaces of the motor. If the motor were having the same issue with the muffs or in a barrel, then I might expect to see potential leakage from a gasket. However, with the issue only occurring under a load it leads me to believe the issue would be Ignition or along the line of the Crankshaft/Thrust path...
I do not know about you, but I hate throwing Parts at something hoping for a positive outcome.(i.e. Very Expensive and not very productive.) I would rather spend money on something that is proven or very likely to be the case.
Thank you for your time and any recommendation you may be able to provide.
