    Optimal prop for a 2004 Trophy 1802 WA with a 125 HP Mercury outboard?

    An old thread, but FYI I have an 1802 with a Force/Merc 120 and I run a stainless prop 3-blade, 13.5 diameter, 17 pitch. I hit max RPM at about 35 MPH. I had an aluminum prop of the same specs before and it went 37 mph. I think that neither of these is right, and I should top out at about 40...

    1995 Force 120 no water pumping through powerhead

    Following up again with more updates. This season my Force engine wouldn't idle. I found that the idle screw of the top carb was way out of adjustment. Did the usual screw it in, then out 1 1/2 turns (I think) at it fixed it. I was still having slow starting. motor turned over slowly, and...

    1995 Force 120 no water pumping through powerhead

    Just though I would check in with some update on this motor. We are old friends now. Every time out something has gone wrong and the motor has shut down. But I have always had my tool box and able to get it running again and home. Here's a list of what went wrong, and how I fixed it. 1) at...

    Force 120hp won't start

    Are you sure the little passages in the brass bolts which hold the float bowls on are not clogged?

    1995 Force 120 no water pumping through powerhead

    Final follow-up on this: Motor pumps water fine now, and is running great. My problem was the plastic sleeve or coupler which slides over the outlet tube on top of the water pump was falling off, or not sealing well to the water tube extending down from the midsection. I put the lower unit on...

    125 force cant find serial & model numbers.

    The serial number on my engine has rubbed off the label. But I checked the title for the boat, and it has the motor's serial number on it (with one typo). I know the history of the boat from new, so I'm fairly confident it is right.

    1995 Force 120 Thrust Washer confusion

    I pulled the prop on my recently acquired Force 120, and it looks like it has the wrong thrust washer. The washer (P/N 75282) was contacting the outer rim of the prop, not the inner recessed metal mating surface, leaving an empty cavity about 3/8 thick which was mostly filled with salt, and the...

    1995 Force 120 no water pumping through powerhead

    Got it, thanks! Hoping for first shakedown run with this boat in the next week or two. Never ending list of things to check or get sorted. OP had the wrong thrust washer, (it was too big, did not nest in hub of propeller) Just got the new one.

    1995 Force 120 no water pumping through powerhead

    Success! Got it all back together on the third try, fired it up and it pumped water out the thermostat hole. So I reinstalled the thermostat, ran it again and water comes out the telltale. Weakly unless I rev a bit above idle, then strong when it revs. Got to check/change the lower unit oil...

    1995 Force 120 no water pumping through powerhead

    Well, I was right about the gap. My mistake was putting the coupler on the water tube, then installing the lower unit with the 5" spacer in place. The hole in the spacer is smaller that the outer diameter of the coupler, so as I tightened the bolts on the lower unit, it pushed the coupler...

    1995 Force 120 no water pumping through powerhead

    Thanks for the response, Jerry. Having slept on it, my current thinking is that I installed that rubber coupler wrong, so that the water is exiting the top of the pump, but not going up the tube. I recall mounting it to the tube, seeing an o-ring on the tube and pushing the coupler firmly up...

    1995 Force 120 no water pumping through powerhead

    Good day, Force-mates I acquired a 1995 Force 120 25" shaft, condition unknown with a project boat I recently bought. My mechanic (45 years experience on all brands, trained outboard mechanics) looked it over and suggested I get rid of it and buy another brand, rather than put any money into...

    Tohatsu 3.5 no spark

    This motor thrown in with a boat I bought. It is the model without a shifter. Hasn't run in 5+ years, but is likely low hours. I cleaned out the tank and lines and carb, changed the plug, use new gas. Get no spark. I suspect the coil. (black plastic thing on side of motor with one big and...
