    40HP CONVERSION TO TILLER

    I am in the process of buying a 40hp "tracker" from a local guy. I do not know the yr yet.. I am assuming it is an early 90's model. I bought it sight unseen, knowing it is probably not running, but it was for the right price. How hard is it to convert this over to a tiller? I am seeing that...

    Adding a Tachometer?

    Is there a way I can retrofit a tach on my engine and not use one of those sensor wire digital tachs that wraps around the plug wires? 96 model 25 pull rope. J25reda

    25HP HEAD COVER TORQUE SEQUENCE

    I have looked in the book, cant find the sequence for torqueing the head cover.. I found the torque specs but not the sequence. I guess start center and work outwards up and down like on the head to the block?

    1981-83 18 hp reverse problem

    Racer, from what I'm seeing, tell me if I am wrong, can that gear assembly and prop shaft be taken out without dropping the entire lower unit? https://www.marineengine.com/parts/mercury_marine_parts/sn/05860644/%20%201018200/677_15

    1981-83 18 hp reverse problem

    I'm about certain it is the dog. it shifts into gear but grinds when you give shift into gear and give it throttle. forward gear is fine.

    1981-83 18 hp reverse problem

    Got er going now!! Looked at wiring diagram, coils  were hooked up backwards. 2 pulls and running. Hooked up to muffs, water spewed out of the thermostat plate. Got one here at the house already. Gonna get a new thermostat while I'm at it and just put a new one in while I've got it apart.

    When you say switch the wires, I assume take them completely off the coils and swap, not cross the top coil to bottom plug?

    So I haven't taken the flywheel off yet, as the weather has been pretty bad the last few days and life hasn't meshed up like it should, I've been reading. Reading my previous post about the timing, and reading my service manual.. its starting to make more sense, as this thing just wont "jump"...

    I wasn't using a timing light. I was manually checking timing using marks on the fly wheel after finding TDC with the plugs out. I have to take the fly wheel off to find the sheared key, which I don't have the tools here to take off. I have a buddy who is gonna come help at a later time.

    So I've decided it's either a sheared key or timing is off. It's showing that it's 5° before TDC. I dont have tools here to take flywheel off to be sure. I'll report back more.. I found TDC And thr flywheel was at the 5° mark according to the line on the recoil as found in the service manual

    I am pumping the fuel line bubble til hard then pulling the manual primer on engine 3-4x and then pulling rope. We had just checked to see if it was sparrking. It has a good spark. I'll try some gas in cylinder and see what happens.

    Got this engine second hand. Non running, has been rebuilt. Had an issue with head and fixed that. Replaced fuel lines and a few other things. Hooked gas and water up, backfired once then remembered I had wrong plugs in, changed those, gapped to .030 and still nothing. Have spark and good...

    25 hp manual timing 1996

    I was just genuinely curious as this engine had been rebuilt prior to me getting it and   assumed someone had the flywheel off.

    25 hp manual timing 1996

    I'm asking how would I set it? Am I on the right path? I honestly don't know much about what I'm doing. I got a non- running, rebuilt motor from a guy for a deal at this point. I have got to replace the fuel lines and replace the primer before I can start digging deeper.
