Just purchased a 98 SNOB. Its been cranking up great but cutting off after an hour or so. I let it settle then crank back up. I believe the boat sat for atleast 2 years. Any ideas on a tank flush or gas filter change?

Mine had similar symptoms after sitting for years - ended up being the low pressure fuel pump. It felt like I tried/replaced everything until I removed the low pressure pump, and could see that it was clogged up with debris. Replaced that, cleaned the gas tank, and installed an inline fuel filter behind the back seat - and have enjoyed problem free boating since. But yeah, you should also install a new FCC filter.

That's almost exclusively when mine would start acting up - about an hour or 2 into the ride. Hook up a fuel pressure gauge to the schrader valve on your fuel rail. If I remember right, you should see about 40psi when it's running right. If it dips when you start experiencing symptoms, then you'll know its fuel. Don't go chasing something electrical if it's not necessary
