View Full Version : Loss of power in turns

I took my 91 Maristar out for a long weekend over the fourth and it ran great until the last day. I noticed an extream loss of power and a strong vibration when in turns and when I had more people on the boat. My prop seems to be fine soooo ... I'm asking where I should look next for the cause.

If you haven't replaced your fuel filter and water separator in a few years, replace them, that may clear up your problem. I just had a similar issue, my '89 would stall on medium & high speed corners. When I checked the filters they looked fine, and I had just replaced them a few years back. But I had run some questionable gas (separate thread on what problems that caused), and even after a carb rebuild I still had the stalling. Changed the filters, and the problem was solved. Particles were too small to see, but were partially plugging the filters.
Good luck,
