Check out the other sections of this site.
Look for posts regarding people trying different props with similar size motors.
Ask for some tech advice from this site & they also sell props

Good to learn how to handle the rough stuff for an emergency but it's best just to stay out of it in a boat that size.

Don't even bother dropping a dime on props or making any conclusions about the boat's performance. The trim ain't workin', so you are not getting out of that motor what she is capable of giving you.

Get the trim function squared away first. Then you can find out the wide-open-throttle top speed and engine RPM. You'll need to get on plane, open her up and trim 'er out/up to find that out. If the prop is buried with the engine down/in, then she is suffocating.

The prop guys will dismiss you until you do this.

Hi Philster,

You are right, i'll repair the trim next week, the mechanics are bussy here, cause the season is starting now.

About navigate with the trim not working,do you mean the prop is suffering and can be damaged?.

Thanks.

Re: Navigating in rough waters, doubts.

If you can't trim up/out, then the engine is hitting a wall. The prop is low, and too much hull is in the water. Lots of stress when you push hard. Bad on the engine in the upper RPM range.

what he probably means is dont try and trouble shoot your prop issues until you get the boat to operate on plane...ie your trim tabs workign properly..

you need to establish a base line to be able to know what direction a prop change ..IF at all....you would need to make.

first things first basically

get the motor running good, set the boat up best as possible, make sure all your adjustables are working and in order.

they could be the floor plan laid out for the most common useage, your trim tabs working as designed, hull clean, trim working on the outboard motor, jackplate (if you have one , working through its range) prop not dinged or damaged...


get that all working good...then you start to play and adjust to get the best speed in the WOT range of your motor....once you get it the fastest you can playing with trim tabs motor trim motor hieght( if you can adjust) ,

the you make adjustments to your prop....( basically trying different pitches and style to get more speed and or adjust your motor rpms at WOT)

good luck
