What props came stock with this boat and what speed would it run with those props?
Individual made mention of a leak back valve that clogged on one motor and having to replace the rubber between the engine and the hull exhaust? Where is a leak back valve on this engine and what rubber would you think it would be?

The only leak back valve that I know of was on my 28SS which had internal flapper valves to prevent a following sea from going into the exhaust.
Why don't you go to St Augustine and take it out for sea trials?

2001 with 26P and I run about the same GPS 72 loaded. I am not hitting the rev limiter and thought about labbing to get a few more R's out of the motor however the stock 26P is a great midrange/cruising prop so I left it alone.
