I trashed that prop on a submerged tree and when I went to order a new one I told parts guy I wanted a prop for a mercury 75 Optimax. I guess I should have been more specific. I guess I should have said a Mercury prop, instead he ordered me a Solas prop for said motor. That took it down to about 42(same pitch). Last year I installed a 24v 80lb I Pilot and extended the front deck back so I could put 2 new series 29 AGM batteries and onboard charger in it, in the front for TM. With this set up I could now remove one of the batteries from the back. Shifting all that weight to the front actually took it down to about +/-38....but it made it fish 100% better, especially in the wind. With that big motor (the 75 Optimax is huge, 386lbs dry) on back this boat always carried its nose high in the air catching wind and bouncing when fishing, now it does not. You might could experiment with prop pitches at this point and get some speed back, but its really not that important to me. I rarely if ever run full throttle anyway.
Nixon, if your stock prop was aluminum and you put on a stainless Solas, try raising the motor one bolt hole on the transome and see if that dosn't help. Stainless needs to run higher than aluminum because of how they bite the water.
