    need a measurement

    Can someone with a set of Mark's mounts check something for me please?

    I would like to know the distance from the top of the front mount crossbar, to the top of the raised nub in the bottom center of the hull.

    Also, a measurement from the forward midwall screw boss to the rear of the motor mount on the engine would be appreciated.

    Thanks

    Help the guy out guys. He is trying to make his own mounts.

    I'll try and get you that measurement from the hole down...but the one from the bottom of the hull would be better.

    Mike,
    I have a quick and easy solution (remember my motto) to that front mount.
    • Cut the front two sides, drill the holes, and install them in the hull.
    • Cut the 2"x2"x1/4" middle piece to EXACTLY 14.25" long. This will automatically give you the correct height.
    • Lay it in the hull, level it and tack it.
    There is your easy way!!!

    Be advised due to the welding angles, you best tack this sucka in about 4 places as well as do at LEAST a partial weld on the opposite side of your main beads.

    Thanks Mark!

    But. . as quoted from your parts list, the front mount is 15.5? Just want to make sure

    I already have the material planned out, and just got my welder from the lake. For the front I am going with 1/8 aluminum C channel crossbar with 1/4 mounting plates Should be strong enough. If I can step on it without it deflecting, I think I'm good.

    Engine Mounts
    • Material:
      1/4" Thickness
    • 304L: Common or 316L: Common in Marine.
    • Wire: AWS E/ER308 or 312 welding wire.

    • Amount: All in 1/4"SST
      Front mount:
      Left side:2" bar x6L"
      Right side:2" bar x6L"
      mid-support:2"x2" x15.5L" angle
    • Rear Port:
      top 2" bar x6L"
      bottom 2" bar x6L"
    • Rear starboard:
      Top 2" bar x 8L"
      Bottom 2"x3"angle x6L"
    edit: I know that the crossbar is not centered. do you have a dimention on that?

    EXACTLY 14.25" long.

    and make sure on the bottom on each side, where it contacts the side rails that you relieve the v-cut to make sure it doesn't touch them. It should only touch the side mounts on the top of the side rails, and both ends of the top of the angle...not the side. I have the flat side of the angle (the side that is cut) mounted against the engine side, in case you ever have to get a stripped bolt out, you have some room to work underneath.

    Thanks Mark. That sit's pretty low. The measurement I got from the nub to the top of the crossbar was 3.375" in case anyone needs to know.

    Sounds about right. I'll try and verify that for you this week since NOBODY else seems to be able to.

    Hi Dan if you're bored, stop by anytime. I wanted to go over a few things with you anyway. . . and maybe rummage through your spare parts pile

    Mark, don't sweat it buddy. I am going to try to borrow someone's shaft. That should tell me everything that I need to know. But, If you do get a chance to measure, I certainly do appreciate it.

    You havent got a shaft yet? It takes him a few weeks to get that shaft done. It's not a one-operation deal. To do any type of final alignment, you will definately need one, and the pump in place.
