by Fred from Independence, Ohio on July 05, 2015
The service was great. The gasket was delivered the next day. I was replacing a Starter in a 1987 GM/OMC Starcraft. The starter was the hardest part of the job. Iboats sent me a perfect replacement starter. The gentleman at Iboats took the time to get me the right parts. The manifold gasket used on the reassembly fit perfect. Thank you
