My first V20

If the water pump impeller in the out drive is over a couple of years old, you should replace it. If you decide to do that, post it here and I can send a plan for a very useful jig that clamps in a vice and holds the lower unit so it’s easy to work on. It even provides a flat area to set a few tools and parts while you’re working on it.

Trim tabs - absolutely.

Tabs down and you can run on slow plane through chop without pounding.

What brand/model do you have?

Scook, would love to see that plan for the holder. Wondering if it can be adapted to an outboard lower unit?

D - pm me an email address and I’ll send you some photos. If you like it, I’ll trace it out and snail mail you a plan. I think from the pictures, you’ll be able to tell if it’s adaptable. I kind did trial and error getting the shape right after seeing a YouTube of a boat mechanic use one he’d made.

It really made the impeller change easy.

Some day I’ll spend the time to get set up to post pictures here - just too busy right now.

I use an old Work mate bench by Black and Decker when servicing a lower unit.
Use the wood vise to hold the unit in place
Not sure it would work for all applications.

Barry, that's exactly what I presently use. Hoping that Scook's plans might be a little better.My biggest problem is trying to use straight clamping surfaces on a curved object. Never really secure and I don't want to clamp the skeeg because God knows they like to break.

I think I'm going to use a profiler and carve out two pieces of 4x4 wood that have the lower units profile (above the anti-cavatation plate) on the one side and a straight profile on the other. Use a router to carve a groove in the straight side to lock into the straight side of the Work Mate's clamping area. Should provide a good solid clamping surface.

That sounds like it would perfect the use of the work mate

Somebody send an email address and I’ll send pictures. You guys who have posting photos figured can post them for everybody to see. Mine doesn’t clamp the lower unit but could be easily modified to do that if needed.
