My old 86 150 Merc would hit 41 mph with the same prop.

Just goin' on about pics, but they're always fun...

MJ makes a good point...if this boat new to him, it could be several different problems...do ya know if the motor's runnin' 100% ??...

well first, is this a new to him boat??

Has he run it before and got top RPM, 5000 to 5500 ?

Or is this a new to him boat and he has never run it before??

New to him then he needs to tune it and make sure that he is getting full throttle and if all that works then re prop, whats he got for a prop now??

If this is s boat that he has had for awhile and all was good before then he has to look deeper!

Need more info!! and maybe skools will see this and be able to help a little more.

MORE INFO!!

If it was I amd its all new to him, I would make sure that the throttle is going full, Then change and gap the plugs, and while they are out do a compersion test.

What prop does he have?? Most run a 17 pitch X 14 1/2 or 15

Hows the carbs?? One or more can be flooding? Does it run smooth?

After he gets this stright he needs to change the lower unit oil and since he doesn't know, I would change the water pump also, Just so I do know when it was done last!!

I've got the same motor, a little older [1992],3 blade no frills stock aluminium 15 x 17. Max RPM is around 5300 at 38-40 MPH. Max rpm is 54-5500 according to the manual. The boat came w/ a 15 1/4 x 15 but I feel the 17 is better all around performance. anybody know the weight of the of the v21?.....Blue, you hearing me??

I think its the same or very close to the same weight of the V20. I seem to have mis-placed my spec sheet ::)

I have one tacked to my office wall (normally). Now where'd I put that thing ???

Dry weight on a 1996 w/150 outboard is 2750 lbs. With a 200 hp Merc it'll run just under 51 mph running a 14x 19" pitch prop. This was taken from the Wellcraft website.
