Hello all. I recently bought an old bayliner with a volvo aq125 in it. I spent a while working out kinks in the cooling system and replacing parts that obviously needed it and got it out on the water for the first time today. It ran great for about an hour. Motor fired right up, ran smooth, quiet and cool. At wide open throttle I was turning about 4800-5000 rpms and it was smooth as silk.
Then all of a sudden it gave a little backfire and died. I was probably turning 3000 rpms or so at the time. The motor turns over strong but will not fire. I took the spark arrestor off and its getting gas. I even put a little shot of starting fluid down in there and it still won't fire. At that point we paddled to shore and brought it home.
I'm leaning towards some sort of ignition problem but haven't torn into it yet. Anybody have any better ideas? Where should I start?
Thanks,
-Mark
