150hp Engine Mount P/N?

[Aviator]

Looking for a new/serviceable 150hp engine mount. March 1973 Parts Catalog shows 12351-12 for 150hp, but others (CC, Kosola) say 150hp needs 12351-15. What's the difference? Wag-aero list their 105, 135, 150hp PMA'd mount as M-235-000 but can't tell what Piper P/N it replaces. Any previous experience? Thanks, Nick

My 1976 Cub Parts Manual list 12351-15 for 105, 135, and 150 hp.
12351-11 is for 125 hp.

Thanks, TJ. I show that too on the North Land CD. I'm trying to figure out the difference between -12 @ $350 and -15 @ $500 (Univair). Both seem to be for 150hp.

It's 150 bucks. :lol:

This is from my foggy memory, so please excuse me if I lead you wrong. I converted my L-21B (PA18-135) to a 150, using the Wag-Aero STC. It called for leaving the -12 engine mount. It is my understanding that the -15 used heavier wall tubing, but to hold each in your hands, you cannot tell the difference. Both are approved for 150 HP.

Ron:
You are correct. I just looked at Wags STC. It says mount # 12351-12.

Thanks, Ron, TJ. As I understand it the -15 is also used on 180hp. (but not the -12), so it must be beefed up.

did your L-21B have the swing out mount

Yes, but I now have so much stuff attached that I can hardly swing it anymore. Hope to correct that during rebuild.

I have a -15 motor mount on my Super Cub. Got it from Univair. It has a reinforcement welded on the right side as seen in the picture. I had a engine mount off a 135 cub and it didnt have the reinforcement.
