[img]Hello, I am new to this forum and pretty much the boating community. Last year I wanted my own fishing boat so I picked up a 14ft aluminum jon boat with a 4HP Mercury long shaft, trolling motor and etc for a steal. Everything works great however I have some questions and an issue that I noticed today.
My transom I measured is 17". My Mercury appears to be a long shaft, my question is where am I supposed to measure the shaft to confirm, and will a short shaft work better for my boat based on the transom length? I plan to upgrade to a bigger motor anyway and the short shaft look more appealing to me and I feel I won't snag as much stuff in the water.
My second question is while heading out and coming in today, mainly at wide open throttle, i could feel the motor almost "slipping" and the revs were increasing. This happened almost every 2-3 seconds when wide open, and when not wide open it decreased for the most part. The performance was lacking and to me its a similar effect to if a car had a slipping clutch. Where should I start to look at to begin fixing this issue?
Attached are two images of my motor on the boat.
Thanks!
