Hi everyone, and thanks in advance for your time. I have a 1988 Bumble Bee bass boat that runs great and I'm just trying to work thru some minor issues with a couple of my gauges. My tach is made by medallion company and I'm not sure that it's giving proper readings. The motor is a v-6 Mariner 150, not a magnum but the smaller of the motors(I'm told) and I can regularly turn 6500 rpm's with a laser 2, 14", 25pitch prop with a cupped face. Not having been around these before my experience is limited but growing all the time. On the back of the tach the indicator goes 1 thru 4 and is currently set on 1, wondering if that is where it should be with my motor. Also wondering if the motor is actually capable of turning this prop that high. The speed is from mid to high 50's with me alone and a moderate load in the boat.
The other question is about the trim guage, which has never worked since I bought the boat in '09. I need some instruction on how to test the guage and sending unit to see where I am with this. Looking forward to your responses, and thanks again for your time.
