2000v losing grip on turns

Recommended Posts

Love my 2005 2000v but on a sharpish turn the prop turbos and loses "grip" in the water unless i slow way down.

I was hoping this was a prop issue but a very smart friend is saying the motor is mounted too high. It is on a jack plate and jacked all the way down FWIW.

Anybody else have comment on this? ive tried various trim settings and nothing seems to make a difference. Is there a way to solve it with a prop even if it is too high? or is lowering the whole thing the only option

Currently have a SS 3 blade prop that makes the right rpms (im not a prop expert).

Love the boat, but running the marsh creeks is no fun.

pic to show just where the JP is set, if that helps.

Thanks!

Put the jp all the way down and take a picture from the back  looking  forward  from trailer level and you will get better replys

Ok, here are the pics, I edited one for reference, so the red line on the motor is about 1 inch ABOVE the red line on the hull. Hope that's helpful.

This is a common problem with jack plates - they add about 1.5" to 2" of motor height even when all the way down.  Your prop doesn't have enough cup to provide the grip needed with the higher motor height.  I would either have some cup added to your existing prop, or buy a new 3-blade or 4-blade prop with more aggressive cup.  Also, I highly recommend negative trim wedge spacers for all jack plate installations (2-degree or for extreme needs, 5-degree).  They really work for several things:  They get the prop further down into cleaner water with less cavitation.  They help for quicker hole-shot when jumping up on plane.  They help to calm down porpoising without as much need for trim tabs.

What He Said^^
 that motor is just on the cuff of keeping the prop in “clean water”  you will need a prop with the ability to not slip in those conditions. Most will say just buy a 4 blade but if you do not get one that has the cupping it will still slip. 
 I personally found a Mercury spitfire stainless prop that worked well on my 16 redfisher with the same problems you are having.

I would go with a Powertech OFX

I ran one of the first PT OFX props on a Pathy...Marcus sugested it back in 2005......they actually had my video on their website...it was F150, 22 V...with a 6" JP.

It was a OFX 18 with 3/8 ported if I remember properly.

give it a try and see how your skiff runs...
