I was out in my boat last week on bago.
17ft Starcraft Alum deep V. I recently added an 8hp kicker (4 stroke). I lost about 5mph, I thought that was quite a bit, at least more than I expected. The boat has an '04 115hp 4-stroke. I got about 40mph out of it before the kicker.
Wednesday I was up north, it started to rain. Put everything away and go. Full throttle, 7.5mph. Obviously somethings wrong...
It won't trim up or hold trim under power. I trimmed it up and as soon as I hit the throttle, the motor came back down to the transom. It trims up/down fine when not under power.
I haven't really looked at it yet, but any chance it's just low on oil? Leaky seal or such? I know those trim units aren't cheap.
Any ideas or suggestions are appreciated. Thank you.
