    Trim Function for Yamaha 90 Four Stroke

    If you have a bad brush or broken wire how does your test find that? I guess it is just simpler to throw a new motor on. A brush or broken wire is significantly cheaper to fix than replacing the motor. DC motors can be tested but I guess why bother!!!

    It needs to go on the opposite side of the post on the recoil. It should push the red arm away from the recoil. As the throttle advances it will push the red arm into the recoil.

    Are Tohatsu/Merc Motors Over Propped ?

    Mine is a real Merc 25. The same motor that was put on many fiberglass Lakeland boats and never had a problem. Yamaha never made a Merc 25 Tohatsu did. It's not that uncommon for the smaller 4 strks to be down on power.

    Are Tohatsu/Merc Motors Over Propped ?

    My 2 strk 25 hp merc spins a 13" pitch prop to 6000 on light hulls. 2 strk Evinrude the same. Something is suspect on the power rating or an over geared lower unit.

    150 Johnson rod bearings snapping

    What is the model # of your motor? My guess is you did not keep the caps and rods together. Since they are broken caps they are pair, rods and caps stay together. The bearings should interchange between rods , not the best practice but it will work. Does your motor have Crank rings? Are they in...
