I got a 2007 supra 21v with the 325 Assault 710 hours. the boat runs okay with no load or pulling the kids no weight in the boat. I might pop every now and than so I know something is wrong.
As soon as I put weight (3000 lb plus of water) in it and go to take off it starts backfiring and dies.
I replaced the fuel filter.
I replaced the plugs around 400 hours but I have never done anything with the distributor cap or wires.
I was thinking a complete tune up plugs, wires, cap. I was wondering where you guys been buying all this?
My only other worry is the fuel pumps. I do have high and low pressure pumps and wondering if one of those is going bad.
But I also think I am pass due on a good tune up.
