"Hi.
Not so long ago I purcha

"Hi.
Not so long ago I purchased my first boat with a 1979 Evinrude 85 hp motor. The boat had been sitting for quite a while before I purchased it and on my first trip out it ran well for about 10 minutes then started running like a hairy dog before finally giving up the ghost. I’ve since had it in the shop where to obtain spark on all 4 cylinders they replaced the starter bendix, the power pack, and the trigger coil. The compression is extremely good for a motor it’s age and the motor now starts easily however the problem I now have is that on the 2 occasions I have taken it out since getting it back, it has run beautifully until stopping for a fish. Then when trying to start it an hour or so later, it won’t catch, and seems to be flooding. I’m hoping that you may be able to offer some advice as to why this might be happening. One other thing I have noticed is that the fuel bulb doesn’t get hard after pumping like it does with my little 6hp auxiliary however fuel does still appear to be getting through to the carb OK."
 
"Hey Clyde, I had same prob on

"Hey Clyde, I had same prob on my 78 140hp. an old salt where I work advised me to loosen off or remove the fuel cap ( I have a 70 ltr under floor) and bugger me it worked, I dont know why, and I havnt seen him to explain. I was advised by a number of other sources, that because of the motors age, and as my day out on the water progressed, that it was possible water was entering the engine somewhere, somehow, (wash or whatever), making it harder to start as the day went on, and the more I would stop and start again. This sent shivers down my spine, as I was thinking id need to replace the old bugger of a motor. Im just glad I mentioned it to a bud who had the same prob, and was kind enough to pass on to me. anyway thats my 40c worth. hope it helps."
 
Thanks David for your quick re

Thanks David for your quick response. I will certainly give your suggestion a go next time I go out. It's not a nice feeling going out and not knowing whether you are going to get back under your own steam.
