I had my '97 GSI out last weekend for the first time this year. It ran
great for about 15 Minutes, but then I couldn't get it over 1/2 Throttle
(about 4500 RPM on the Tach) without it bogging down. I ran it slow back to
the ramp & pulled it out of the water, no problem as long as I didn't try to
go over 1/2 throttle. Seems like it could be a fuel problem. I always
leave under 1/4 tank at the end of the season, add stabilizer, then top it
off with fresh fuel in the spring as well as replace the spark plugs.. I
checked the spinoff fuel filter, it had a few particles in it but nothing
major. Are there any other filters along the way or should I go after the
Carb next? My GSI has a total of 114 Hours on it. Any suggestions would be
greatly appreciated.

Thanks in Advance,
