This is my first boat, paid $3500 for it and still spending money.
$250.00 for Bennett trim tab pump. The electric motor burned up and tried to find a motor for it, no such luck. Waiting for the pump to show up.
$165.00 for 280DP parts. Replacing the bellows, u-joints and steering yoke bushings. The steering was real sloppy and while I'm into it this far, I might as well replace everything else.
$110.00 for a new throttle cable. Replacing the P.O.S. cable with one from Control Cables. This one had a kink in it and wouldn't let the motor return to idle making it hard to dock and hard on the sterndrive.
$60.00 for a universal tank selector valve and new fuel lines. The boat has a manual selector valve now, but I'm replacing it with an electric one so when I switch the gas gauge on the dash, it changes to the same tank. Prevents from reading one tank and pulling fuel from the other (in my case, keeps me from running out of fuel thinking I have a full tank....duh).
Not complaining by no means, never had so much fun spending money. And yes, I do all my own work.
