Boat has ran stellar all season. It sat for about three weeks, then took it out last Thursday. Fully up to temp coming out of no wake, I rolled into throttle, planned out and mashed it. Sounded and felt like one week hole.
Plugs are a year old cap rotor and wires three years old. 93 octane non eth. Rebuilt Qjet in '12 with brass float (original neoprene was sunk), boat has never missed a beat. I can get it to miss by getting on it hard from about the time secondaries open 3300-4500.
I may take it to the lake here in a little while, take a look at the plugs and swap plugs with the last set that I had that worked. If not I'll at least look at plugs and verify there's no whiskers. Might pull the cap and have a looksie.
I was told by original owner that he replaced plugs every season no matter what..
May have been a reason he did that but I think it was the way the carb was set up from factory. It was non regulated putting out 9 psi, couple years ago when I bought it the oil smelled like gas, I jumped the fuel pump and saw fuel running down onto the butterfly. That's all been solved, regulated down to 5 psi to where the carb can hold it back.
The other thing, I did a compression test a few years back at Elsinore and two cylinders were lower than the others. Likely due to the exhaust riser leaking, maybe got the valves crusty, since then fixed and runs with no issues.
94 marine power 454 close to 700 hours, valve job couldn't hurt, but the damn thing runs so good I don't want to fuck with it. Anything else I should be looking for? I don't want to start buying stuff to throw at it.. Eventually motor will come out for a freshening up but that may be years from now as long as it runs the way it always had up until last Thursday.
