You guys have been a huge help to me in the past on a little 15 hp Mariner. Was able to do the work that some of you suggested myself, and haven't had a problem since. This one will be out of my league.
My son came about a 23' fiberglass boat with this Yamaha 250 on it. Owner had just gotten a new rig and wanted this gone. Told son that he
had bought the motor new, had it installed on boat, and had had it serviced by dealer once a year. Sitting on galv. trailer. Used in salt water.
Let a Yamaha dealer check compression, said perfect. Motor runs very well for a little while, then starts to get hot, seems to go into limp mode if it has such a thing. Replaced water pump impeller, have not run yet, but worried that old one did not look bad. I'm thinking it's not getting enough water, maybe corrosion.
Mfg. date 07/2002, other info is: Z250 turb, 60V U 10002 HPDI
Any thoughts? Thanks much. We are on the GA coast.
