23 sceptre performance

[merch]

Hi,

New around here. I'm currently in the market for a 23' potter hull sceptre. I've been using this site as reference during my search and truely appreciate the body of information you guys have assembled here.

I have a question regarding performance of these boats. In my experience so far most owners trying to sell exaggerate quite a bit, and in each case the seatrial has told the story.

I've test driven two types so far. One with an inboard 230 yanmar that was converted years ago from and I/O to a full inboard. It lacked the tunnel drive and prop/shaft was angled below the keel. between 3300 rpm the boat settled in between 15-17 knots depending on tabs. Maxed out at 3600 rpm, at around 21 knots. Boat was likely propped wrong (14-3/4" diam, not sure of pitch).

The other boat was another I/O conversion. It had a flotation bracket with a 2000 225 OX66 yamaha. At about 4000 rpm this boat would run at 16 knots. Topped out at 5200 rpm (should be higher I assume) at about 23-24 knots. Boat had a 15"-17p prop on it.

What I haven't tried yet is one that is stock with an outboard on the transom.

In both cases the boat started to "feel" right in the low to mid 20's (knots) range. My question is, anyone here running a 225 (four stroke or 2) that would be able to offer some performance info? Is a 250/300 more appropriate for these boats?

Anybody locally with a sceptre that would be willing to give a guy a ride (not neccessarily sell, just a ride)? I live in the Buzzards Bay area and would appreciate it tremendously.

Thanks!

Tom
