I think the transom jack helps as well. Haven't had much of a chance to play around yet but I did notice when I raised the motor to the top it had the same effect as increasing the throttle - boat lept forward.

Mid setting on jack full throttle = 5500rpm and 41kts on the GPS - think a 21" no prob but as you say a 24" will prob not be too good - having said that it MAY work on the jack when deep in the water - for 49 it had to be worth a try!!!

As I understand it, lowering the jack effectively lowers the revs, and a larger prop effectively lowers the revs, so all this will do is increase the load on the engine.

For your 45 though, a good buy as a "get-you-home prop".

Good point - you are right of course - brain suffering meltdown at moment sorting out large VPN project through some crappy old routers!!!

Lowering the foot in the water increases overall drag. Depth of the prop alone should have no direct effect on rpm until it gets really shallow and ventilates.

If you find the boat goes with the 21" prop, take the 24" to a prop shop and have it repitched to a 22". It'll make a good light load prop. Certainly cheap enough.

Congrats, Cod; great looking boat.

Looks fantastic Codders, and it looks bigger than it's quoted size too.

I guess like me you'll find a few minor bits to tidy up such as you bilge sump. I also spent a good while tidying out the wiring on mine and upgrading to proper tinned marine cable. No point having a boat of that value with crappy automotive wire corroding by the day. Check your junction boxes to make sure they're actually sealed properly with watertight glands. Mine weren't!

And that's a good turn of speed for something that size. I reckon they're an economical hull with good performance for the size. Though I wouldn't fancy carrying half a ton of petrol everywhere I go!

Something like that - I think getting my boat was more of a challenge than beating Trinidad and Tobago though!!!
