Running a twin engine boat on only one engine.....Good or bad? If I'm just looking to ensure leaks are fixed and seals are solid, still waiting on getting the other motor going.

On the hose....you should only do one at a time anyway. in the water......you can, but won't get on plane, just idle speed. (trying to get on plane will only blow your drive)

Thanks Brother

On my numerous drive blowing adventures,
those resulted on running back on only one engine.

Like what HP said, you wont be able to run it up on
plane though.
