Location: Rhinelander | Ran a 23P Merc Alum prop last night. Max RPM's hit just over 6000 on the tach, GPS speed was a touch over 50mph but I was running out of lake......could be slightly more.
The old efi has a max of 5600 rpms...23P may not be the right set up. The vent holes in the Tempest prop, which was on the boat at purchase, must need the plastic inserts to even run half way decant.
I'm hesitant to even stick with the 23P SS Tempest.....Plastic inserts are an order item and this may not even be the direction to head.
We're trying somthing different tonight, just don't quite know what yet. Note: Buddy owns a large dealership but does not sell fiberglass boats and engines top out about 150 hp. He is very knowleable but other ideas and pointers always welcome. |
