    Question My Rail Mount Wheels are Turning...

    I'm determined to use my top-mpont 3 bolt Prestolite starter...and I saw the pelow pic and my feeble little brain started to think.


    So I'm thinking (smell something burning)...WHY couldn't I cut my current 3-point bell housing (see cut line) and weld a rear plate to it thus getting a rear bell housing/starter mount AND engine plate all in one???

    Couldn't you just use a rear motor plate drill and tap it for your top mount starter. Mount it to your motor and then use spacers to bring your starter back?

    AND...I'm also pondering, when I add a Jet-A-Way, my engine will be some 4 & 1/8" forward...(and exposing access to my suction housing)...I could fab up a pump brace off the 4-loader bolt bosses in the suction housing!
    Uh...too much time on my hands???

    "rear motor plate" directly to the engine???
    Not enough clearance for the flex plate.

    Whatever is bolted directly to the rear of the block must allow clearance for the crank shaft flange, flex plate etc like the very top pic. some type of bell/shroud would still be needed.

    Gotcha.
    I have a rear motor plate that has a cut out for the flywheel and is drilled and tapped for the top mount starter, and has a cut out for the started gear. To eliminate the bell housing completely. That's why I ask.

    Could you post a pic... I'd like to see it.
    I like the idea of some protection/shield around the flex plate, u-joints etc (if) something were to come apart.

    Hammer, I can understand wanting to keep a top mount starter and even wanting to keep the Prestolite since you've kept it working for so long, but............that thing is butt-ugly! Here are a few pics of rail mount setups with top mount high-torque mini-starters:

    This one belongs to Cyclone


    This is on Steelcomp's old boat


    Not sure whose these are, but both were taken a Ming a couple years ago.

    Nice idea by oldsquirt.

    Then you can just send me the old Prestolite top mount. I'll be happy to take it off your hands as a spare for mine, free of any disposal charges.

    PM me for my address.

    Steelcomp What brand top mount is this? Is this custom?


    Hammer, I made this pump brace out of 1/4" 6061 Aluminum.

    Thanks for the feedback/suggestions fellas.
    Several years ago I spoke with Greg Shoemaker and for whatever reason he said my big, heavy Prestolite 3-bolt top mount starter was "worth it's weight in gold" why he said this beats me but, it does spin the heck out of my engine and has never let me down.

    PS...I'm not looking to slave over polishing engine and rail mount brackets etc...for this boat paint it black and call it good to go, just as long as it's a clean looking assembly.
    A new black paint job on my "but ugly" starter will make it down right pretty lol
