ok so ive got my first boat and it came with a good running 140hp tower o' power. its been gone through by a shop and is in excellent shape. from what ive figured out about it is its a 1978 model. so i want to go out and play now. out here in san diego just getting to a lake, paying for lake fees, finding one you can actually touch the water, and all the other fun stuff seems like a pain in the A. ive got oceanside harbor 15 minutes away and is only a few bucks for parking. my question is, how well do these hold up to salt water? i know to flush the motor every time i take it out, keep an eye out for corrosion. am i just asking for trouble? thanks for any advice.
