    Tilt trim Question 1988 40 John.

    I recently acquired a 1988 40HP Johnson. I am in the process of rebuilding it. The tilt trim is the bolt on style. There does not appear to be any requirement for relays as the 4 pin connector from the remote matches the 4 pin from the trim motor. Three pins are used, blue, green and ground...

    2006 MFS25B Tohatsu

    I can make the tilt trim go down but not up. The relays are activating and I can get +12volts at both the motor wires, separately by using the switches. can run the pump up and down powering directly from the battery. Initially thought bad relay but no change with a new relay. This motor could...

    1999 50HP johnson T/T

    The unit is off the motor and on the bench. The cylinder cap is freed up. Most oil is drained out. Opened the manual valve. Need to pull the piston and rod out but have a strong suction holding it in. How do I release the suction. A bit wary of running the motor.

    1975 9.9 Wizard

    This motor will not come up on revs. I notice that there does not appear to be a fuel pump. The tank is new and of the all garden variety, not pressurized. Is there some sort of pump built into the carb? Any input would be appreciated.

    1997 60* Evin 90HP OIS. Past 2200 fades and dies under load.

    Have done all the usual fuel supply tests and no improvement. There may be more to this story than we know. This motor supposedly has been rebuilt. Comps are normal, sparks are normal. It fires up ok but dies when throttled up. It had a single standard fuel pump fitted in place of the VRO...
