    something to think about the last 3 plastic thru-hulls I had to replace was because the flange broke off. plug would not help that situation back to the leak. double check all the thru-hulls then look at the rivets/seams

    leaking riveted starcraft ('82 MR180)

    Remember, livewell pumps are rated at 0" of head. So if the rise from the pump to the discharge is 1 foot and you have 6 feet of hose (~1' of additional head) you have to look at the chart for the 2' of head. Which is closer to 600gph

    Rochester hasn't made a carburetor since 1989.. Volvo Penta has t used a non-holley carb since 1988. So what did you buy? If you want fuel economy, get a sail boat
