    Tons of power in bucket, weak on water

    1990 15 hp long shaft motor. It was previously running 17 mph wide open throttle pushing my Jon boat. I ran some questionable gas through it, and I was needing to completely rebuild carb so I went ahead and did that. Also new fuel lines, new fuel pump, new cam roller, impeller, gear lube etc. I...

    Test for bad motor mount?

    Is there a way to test to see if one of my motor mounts are bad? I have a suspicion this maybe the case, but I wanted to check to see how to definitively tell. Thanks in advance.

    What causes this?

    I have one more question regarding my new motor. Working on it tonight I noticed lots of play from the cowling to the throttle. What causes this and what is repair (if necessary)? I’m hoping video helps explain it more than I can. 1990 15 hp for reference. Thanks in advance!

    How to get my throttle roller closer to the armature/flywheel?

    Recoil repair

    Got the spring pinion put back into place. Easy fix. Next thing is my recoil is sticking and not allowing the rope to return freely. Does this mean probably needs a good cleaning?

    Is the driver coil the red coil with what looks like medical tape under the flywheel?

    1976 25 hp, no spark

    Someone has lost the bolts that hold the recoil in place and the electric starter isn’t working at the time is reason for using the drill. I’m going to try to find bolts for recoil today

    I’m not quite sure where to go from here to get spark besides replacing the coils unless there could be some sort of ground issue?
