Full StarFull StarFull StarEmpty StarEmpty StarCheck threads
by Jeffrey from Bremerton, Washington on April 15, 2015
The manifold feels solid and should work great. Before installing make sure you check all of the threaded holes for the cooling system. The mounting holes for the heat exchanger were a different size than what was on my boat originally, so you may have to buy new hardware or tap the holes. Also, the hole on the front end for the plug wasn't cut deep enough for even the shallowest flush plug I could find, so I had to buy a large tap to make that hole bigger. All of this would have been much easier if I had checked before mounting and had to pull back off.

Full StarFull StarFull StarEmpty StarEmpty StarDon'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
