performance enhancement (maxing out hp)
Posted 16 July 2017 - 04:21 PM
It actually scoots along pretty good. Getting up around 25mph on the GPS. Hole shot is not great. And in order to get up on plane quick, I need to have weight in the bow (fill the livewell or get buddy to sit up front)
The boat is rated for a 40. So I'm at 62.5% of rated maximum.
A 30 would put me at 75% and if I could find a 35 I would be at 87.5%
So, my questions...
Will I notice a big difference going up to a 30? Or am I better off to be looking for a 35 or 40?
Thanks for any input you can offer. I'm very happy with my new rig. Not looking to be the fastest 16 footer on the water, just looking to boost performance a little.

If you want maximum power and speed go with the maximum HP rating for the boat.

Before you go that route, have you checked to see if your Prop is the correct size? Maybe a 4 blade would help - from what I understand it drops the top end speed, but makes the hole shot/handling better. I will probably go that route myself, and keep my current 3 blade as the backup.
Anyway - might want to check that first, as it is much cheaper than a new motor - lol.

5 hp won't show much increase, especially if you go from a 2 stroke to a 4 stroke.

If you're going to upgrade your horsepower? Make it a one time deal and get the 40.

A further on Tupelo's post.
First make sure you have the correct prop that is maximum for the set up of your boat as you normally use it.
The best way to do this is by running your boat wide open on flat water and checking the RPM.
Next compare this to the maximum rated RPM for your motor.
Is the RPM within the maximum WOT range recommended by the manufacturer?
If yes than you need more motor for better performance.
If no you can improve the performance by changing props.
If the difference is minor than the improvement will also be somewhat minor.
But if your boats RPM at WOT is far out of the maximum range than the improvements can be very noticeable.
Sometimes there is no replacement for HP though.

Problem I'm running into is that I don't see a whole lot available in the used market.
You may not see them but they are out there.
What I mean is place an ad posting what you want and that may provoke someone with a 35 or 40 wanting to jump to a bigger unit as well for their boat to reply and make you an offer. Ad's are free so no harm there right?
Good luck and yeah MAX it out like the others have said.
