Too Small
by Edward from Walnut Creek, California on June 10, 2013
Does not fit - too small to match bolt pattern and cutouts for port openings nothing like the OEM gasket.

Don't forget the hose nipples
by Eric from Sandy, Utah on June 16, 2011
The manifolds fit great. Sierra needs to include the hose nipples in with the mounting kit. There are threaded holes on either end of the manifold and the kit only comes with the drain plug. I was unable to remove the hose nipples from my original manifolds, and was unable to find the part locally. I had to go to an industrial hose supply company to fabricate the part. If you don't want to go through all that trouble make sure you purchase the hose nipples from the Volvo Penta parts area on iboats.com
