The product matched the original for my Volvo Penta 5.0 fix with SX drive. The vendor shipped promptly and met all expectations. I ended up not needing the part and returned it unused without issue.

Le cœur n’est pas aligné. inutilisable, incapable d’aligner le pied. Enlever et acheté une pièce d’origine pour régler le problème. Argent jeté aux poubelles.

Fit perfect on my 1989 4.3 with Cobra outdrive. Spun my previous one running a prop with too much pitch. Ran great at high speed but the 4.3 with 4 barrel quadra-jet over powered the previous coupler. Pay when you play. Haha

Great quality product, looks like it'll perform well. Just waiting for the spring to put the boat in the water to test it out

Take a look at the photo. The rubber is soft, you can push a finger into it. Made a phenomenal mess in the engine compartment when it blew. Didn't last 2 boating seasons, and was never under heavy load. Too late to even ask for a refund or replacement.

Be aware of the casting/machining of these where the bolt holes are. Where the nuts sit on top of the hole, it is not true and flat. Your nut will be offset and not bite all sides when torqued.

Awesome products, make sure to get a right dash number, there is dash -1 and -2 depending on the hole placement. Amazon customer service is also amazing, had a problem with a order and they fixed it within minutes. Thanks guys!!!!!
