    1988 Johnson GT 175 fuel starvation

    I just checked with my 2 neighbors compression guage. One gauge read 75 on all cylinders and the other guage read 70 on all cylinders. Guess my 2 cheapo gauges aren't very good.

    87 125 force

    Just got my Michigan Wheel Vortex prop in today and after getting it put on I noticed that there was a gear case seal for it. I'm guessing that what it is ,it's a small plastic piece that goes around the end of the prop that sits against the gear housing. This prop is really made for a 88'...
