prop for tabs 5m with 115 etec

[Outsider1]

Okey dokey,
Raised the engine to the highest position, and took out for a run. Very similar WOT speed and revs (about 5500 @ 34ish knots) to the 3rd hole. Only diff really was the motor spins the wheels a little, if not trimmed out correctly getting out of the hole, no drama really tho. So looks like i could play around with the props now? At 5500 WOT, is this gonna do any damage to the engine? I pretty sure BRP recommends 5500 to 6000 (max power/engine efficiency at 5750), so looks like it could go up a tad......... any thougths?

You have it much close now lamontsa. Your motor should not suffer any premature wear from lugging if you are getting at least 5,500 rpms.

Optimum WOT rpms for your model 115 hp is 5,600 to 5,700 with your normal load on board ie fuel, fishing gear, passengers etc.

I would suggest you post again on the E-Tec forum and ask what props to try. If you can find an E-Tec dealer that can organise a prop trial for you it should not be too time consuming. Having said that you will only get another 1 perhaps 2 knots out of her I reckon, but holeshot, economy and cruise should also be a bit better and worth the extra effort to get her just right.

You really have to wonder whether the original owner sold it because of a perceived lack of performance. It goes to show you how important a good dealer is in the first place in getting the motor installed and set up correctly. Makes all the difference!.

Cheers and good luck with the testing.

I have the same boat with a 115 merc 4 stroke with a 4blade trophy prop and my boat is good for 48.

Hey Fin101,
You have the same boat as me - Tabs 5.0 Terr Pro? and same power, but 4 blade prop, and your gettin 48 knots or mph?
I have asked on the etec owners website, and it was suggested i try a 4 blade rogue prop..... the 4 blades are apparently a bit better for stern heavy boats.... Do you have any specific details/model number on your prop?

Thanks
