Well, here goes.
Last year before I put the boat away the engine was bogging down under throttle. It happens about the half way point but powers through it and seemed to run fine at higher rpm.
Following that I had the carbs etc cleaned. Tank and lines checked.
Lately prior to getting the boat in the water, on checking the oil there is what I believe a slight smell of petrol although not conclusive. After research it seems the diaphragm can become torn, putting fuel into the oil. There was no doubt some fuel in the pump and lines while the boat was parked up over winter, so I'm thinking it ended up in the engine?
I'm getting it serviced next week so will keep an eye on the oil condition once I get it back in use.
