Location: Sun Prairie, WI | Well I will find out today or tomorrow if I get the new motor or not. Acording to the book I have the max rpm for the 75 is 5000 to 5500 and the 90 is 4700 to 5300. So Im thinking that the 90 with the same prop and go up one hole may get me right where I want to be.
I don't know how much life is left in the 75. Been acting kinda strange lately. Touchy to start one after fishing a spot and motor has sat for an hour or 2. also seems to fade out alittle on the top end. Just hopin the 90 is in better shape so I can get a few more years out of the boat before I get to buy a newer one. just did a compression check on the 75 and its around 115 on all 3 cylinders. any idea where the 90 should be for compression |
