Wot 120

I have a 120ld90a 19 ft capri bow rider jus wondering what my top speed should be and Rams at wot?

5500 is the WOT for a 120 - 1990 - 1994
5250 is the WOT for a 120 - 1995 - 1999

That should put you about 38-40 mph with a 17p prop. You want to pick a prop that will get you to at least 5000 rpm. At least that is my experience.

It's a 1990 with original prop can I change the the prop if so what do recommend

 

[SkiDad]

you have to take it for a test drive and see what your max rpm is - if it's 5000-5500, leave it as is... if it's under 5000 go down in pitch - say from 19 to 17. Most likely you have a michigan prop.

The original prop should have a mark somewhere on it telling you what size it is.
If it's an aftermarket Michigan then it will have a series of #s and letters.
Post what you find.
The 19 Bayliner with a 125 can run anywhere from 35-45 mph.
Do a compression test, then unload all the extra stuff on board and go for a ride.
Most people(me too) carry to much extra crap and it all adds up to slow you down.
Run it 2-3 time at wide open making sure the motors trimmed right.
Post the results along with the prop numbers or size.
Pretty sure you probably have a 19p maybe a 17p stock prop.
