    Force lower unit on Force by Mercury top end

    I've got a Force by Mercury top end (40 hp, serial number puts it in the 1992-1994 range) that runs well. This motor appears to utilize a Force by US Marine block with Mercury components. I've also got a gearcase from a 1989 Force by US Marine 50hp. The older gearcase will bolt up to the top...

    99 Ficht 90hp Tilt and Trim question

    I'm working on the tilt and trim from a 99 Ficht 90hp, but I'm doing the work off the boat. I've filled the reservoir and cycled the tilt cylinder several times to release any air. The tilt cylinder runs up and down great. The trim cylinders won't cycle down. I can push them down if the pump...

    Mercury Trim Cylinders won't retract

    I'm trying to refurbish a tilt n trim unit from a 1985 Mercury 200hp which has been sitting for a while. I had to replace the motor on the hydraulic pump. At this point I'm just cycling the PTT using the two wires and a battery. Both the tilt and trim cylinders will run up without any...

    Installing water pressure gage on 1977 Evinrude 70hp

    I recently re-powered with an older Evinrude. The motor is in great shape and runs fantastic and I'd like to keep it that way. I'm a little nervous about not being able to monitor water flow through this motor (it does not have a tell-tale) and would really like to install a water pressure...

    1984 Mariner 50hp Tachometer and RPM questions

    I have an '84 (may be an '85) Mariner 50hp. It's a 4 cylinder. I've had this motor for many years, but have never had a tach. I've now installed a tach and have a couple simple questions that I'm struggling to find answers for. What is the recommended WOT RPM range for this motor? I've...

    1987 Suzuki DT85 overheats at high RPM

    Re: 1987 Suzuki DT85 overheats at high RPM I didn't run the pump immersed for a long time with the motor. I was worried about mucking up the impeller. But, it seems like it would be tough for the pump to pull water up several inches. When I hook the hose up with low pressure, I don't see...

    1987 Suzuki DT85 overheats at high RPM

    Re: 1987 Suzuki DT85 overheats at high RPM It isn't possible to just immerse the intakes and have the pump work. These pumps can't suck up water from below - they must be fully immersed. After trying it, I had one of the those 'well, duh' moments. Anyway, I rigged up the muffs and ran the...

    1987 Suzuki DT85 overheats at high RPM

    Re: 1987 Suzuki DT85 overheats at high RPM After first managing to lose the motor cover off my 'kicker' (a mid 60's Johnson that belonged to my grandfather) on the drive to the lake, I think we made some headway. I ran for quite some time at WOT without the alarm. At one point, I pulled the...

    1987 Suzuki DT85 overheats at high RPM

    I recently acquired an '87 DT85. The motor had a known issue when I bought it - it overheated at higher RPM (3500+). I hoped that with a little effort, I could resolve the issue. Unfortunately, that has not proven to be the case and I'm out of ideas. The motor is currently installed on a 16'...
