Maximus on Speed!!!

matt h · 09 March 2009, 22:34

New engine went superbly, reckon good for 45 kts with that super slippery prop on!!

JSP · 10 March 2009, 21:13

Looks a very tidy RIB

John, it transformed the boat, had a Mercury 75 f/s on before, 33 kts was its upper speed,
Max had fitted the new 130 e Tec with a underpropped 17 pitch and achieved 40 kts, going to try a 19 pitch prop which all revs considered should achieve 44 +, yeeeeha!!

Good stuff! Tell him to lay off the speed though, the come down aint worth it

Did he pinch the Etec or was it cold

I doubt whether you'll get another 5 knts. Jim, myself and DHDai are running max HP boats, to achieve a 2knt improvement though prop tuning would be a major result.

There are not many ribs that get too far past the 45knt mark.

Well, there are quite a few... but the fuel bill sucks :| At 54.1 kts im using 120l/h :| - mind you that is for both engines

Thats true.. our zapcat can hit about 40 knots with a fat git on it like me... probably a little more with less ballast

That could be faster than the 6.5 Vipermax with a 150 Etec

To tell the truth it wasn't me who clocked that speed, it was Mr Manning.

Yeah
"Respect my authorityyyyy"

Slightly contrary to the owner of the Scrote Boat...

Maximus achieved 36-37 knots at around 5000RPM without going to WOT on Saturday running a 17" Viper prop. SO I reckon that prop will see 40-41knots when at WOT. If it can pull an 18 or 19" prop then 45 knots could be achievable
