Hello all.
I bought a boat with a Mercury 50hp 1983 4 cyl last year. I went through the entire thing and replaced the stator and trigger as well as rebuilding the carbs and syncing things up. It ran excellent for about 25 trips last year and 5 this year so far. The first 3 times I had it out this year, it started as usual. The last two times out were hard starts, requiring about 6-7 cranks to get it going. Once running, I could turn off and it would start with one turn of the key every time. I decided that try to crank it over in my drive way before I went out yesterday. I could not get it to turn over at all. I noticed a leak in the fuel filter (cartridge type), and I couldn't find a gasket, so I went to the dealer and got an inline filter to see if that was the issue. It still won't turn over.
Things I checked to day below
I've checked spark to each plug an all are strong
Tested each coil and they test within range
Switched tanks to try different gas- I used gas from last year but I had since run through that tank and new gas is now mixed in with the new tank. The fuel was stored with Stabil and there were no issues on the first times out with the old fuel
I'm not sure if this is an issue but I can't seem to get the fuel filter to fill, it goes about 3/4 of the way and it feels like I'm fighting against something. The bulb stays somewhat firm.
One other detail- when I try to start it, I get a definite pop like it's igniting but it's only a single pop and it won't do it again after the initial tuen of the key.
Any ideas?
