Outback.. kinda slow.

So I have an outback, and did a WOT test yesterday, with nearly empty fuel tank, and 4 people, stock OJ 13x13 prop. 3 blade. Wot was 38 mph on the speedo (forgot to check PP) and 5050 on the rpm's. Shouldn't I be getting to about 5200/5300 on rpm? Also thought top end should be about 44 mph.

Did you GPS check it? Could be your speedo is a little off. Also when I went from the stock 13.7x17x5 prop to a 14.25x14.5 on my mobius I gained a little on the top end because with the stock prop at WOT i could only get to 4500 rpm max. With the wakeboard prop it would actually get to max rpm at WOT.

usa - Your max boat speed should be in the 40s. If memory serves me correct, last season my '07 Outback at WOT hit 45 mph, running w/ factory propeller. - Deerfield

All depends which motor you have. My 99 0utback would do 44 at 4500 rpms with the stock prop. Did both speedo's register same speed , and as above , I'd check it against gps. What did you used to get speed and rpm wise?

I agree with Deerfield, stock prop and WOT should be just under 5000 rpm and around 44,45 mph.

X2 our 07 obv would do 45 to 47 wot on glass just me same stock prop.

going to have to do some more tests with the stargazer gps. I think with it off, it will tell you the speed.

Owners manual for your boat states 4400-4800 WOT range if you have the 325 hp motor.

[usaski1]

Strange, if 4800 is max WOT, why would the rev limiter be set higher? I know I saw 5050 on the digital tach (perfect pass)

Found my Perfect pass to be a little tight and WOT was not really WOT. Although, your RPMs sound about right.
