tig welding

[johnsonm50]

Why not pick up a Yamato tower and make a powerhead adaptor plate. This is a lot stronger, and will get the overall length of the motor down to work on a hydro . Unless you plan to troll with it you dont need a water pump. We put a Yamato foot on a 55 H and it cools fine .

No trollin, its a play motor and will be goin thru some white bouy zones, Thats a good idea tho, Im just messin with what I have. Thanks.

Not sure what he used but it seems to be good quality well penetrated bead. He told me Merc aluminum welded well. I got no absolute answer on alloy content . Since only the outside could be done I epoxied a stainless steel pipe in the driveshaft hole and epoxy & screwed a plate on the back across the weld area to be cautious on the side of possible error. The low tower mount is below the weld and I made a bracket to take the flex out of it so the odds of losing the foot are low even if it fails.
The driveshaft is being done now and its got a powerhead on. I hope to test soon.

Been awhile but I finished this project, its ready for a boat test. Heres a pic,, needs a little paint touch up but beauty aint the goal here. It runs & seems to be smooth.
