What style prop do we like on a 20' Sceptre

[Basketcase]

Its time for a prop. This one is old, dinged up, and just tired. I want a new shiny stainless one. I'll keep this as a back up to get me home in a situation.

My setup is a 77 20' Sceptre with 2005 Optimax 175 on the transom. Its a 19pitch aluminum prop. RPMS seem fine. Cruising at 38mph at 5k rpms with more to go. I've adjusted motor height to where it should be. Plate visible at cruise.

The question is do we like 4 blade or 3 blade props for this boat? I know the typical ins and outs of a 4 blade vs 3, but I thought maybe there were more things to consider when its on a Sceptre, due to its different weight setup.

What I do notice now is it blows out easy in tight turns, or even when trying to accelerate after a quick drop off plane. But mostly turns. I don't think it was like that until I brought it up 2 holes. The plate was well below the water on plane before though.

The use of the boat is as a utility to carry stuff to and from the island house. We also fish a lot in the bay, and probably will venture out a bit to open water, but rarely. The bay can get ugly so a slow plane speed would be preferred. Obviously I have a 175 so I want to go fast too!

Suggestions?
