make sure you order the right manifold
by Timothy from Port Townsend, Washington on October 06, 2013
I was happy with this manifold this time. The only problem is make sure you order the right manifold, I ordered the wrong one the first time, the discription said it would fit, I put the side plates on then tried to put the manifold on the head and it did not fit so I sent it back and they said that they will not refund my money because the side plates were installed.

Product was fine. Logistics at iboats getting the product shipped in a timely manner needs work. It was not shipped for 24 hours after I ordered the product.
