tomcat permatrims

So now that I have the new engine, i have one with a permatrim and one without. So do I take all the permatrims off or put the old one on the new engine? I'm not in a big hurry to start drilling.

On the Tomcat, I would think you would want the Permatrims, and since you still have the old one, I'd pull that one and put it on the new OB. But then, I'm not a Tomcat driver, so maybe there is no need for being able to push the bow down into a chop. They might help add some slow speed directional force for steering aid.

Easiest seems to be taking the one off and trying the boat without it. If you're not liking the results you can always buy one more and use the first one as a template to drill the new motor.

On the other hand, if you had started out without the Permatrims on your TC and liked the improvement they added when you put them on, then you may as well add the second one now.

When I went from the old Honda 130 to the new Suzuki 200 I figured I would be putting a Permatrim on like I had for the Honda, but the performance turned out to be so good that I didn't need any of the benefits the PT would add. I still have the nagging question in the back of my mind about whether I would gain any fuel efficiency with one, though.

Good to see you back in business! I think you made the wisest choice by going with a new complete replacement motor.

Oops - I see by Harvey's comments that I forgot you already have the second PT. Still, I think I would try it without first if you are not sure.

Conrad,

A controlled experiment info would benefit us all.

However, I would first confirm with your dealer that drilling holes in the cavitation plate of your new motor would be covered in all warranty issues regardless of how 'harmless' it is ...as we all know.

Maybe I'm paranoid, or maybe Honda lawyers are better paid than yours.

Best of luck in any event! We think you made a very wise choice in difficult circumstances and wish you better luck in the future.

Cheers!

John

I ran my Tom Cat for about 200 hours with no Permatrim--2 150 Suzuki, Stern lifting 4 blade props, almost 50 mph WOT at 6K RPM>. Because I wanted to see if it would plane at a lower speed, I put on Permatrims.

I would say it was a mistake. Took a couple of MPH off the top end. At low planing speeds, it thru a wall of water, up over the cowls and onto the bracket. I didn't take the Permatrims off, but I didn't try and plane at 9 to 12 knots again. It was OK (only transient "wall of water" as we came up to speed...

May be different with the Honda 135's.

I suppose i'll take the other permatrim off and see how she rides. If she rides well I guess i'll be using some bondo on those holes.

I installed PermaTrims on our TomCat (Honda 150) and loved them. I never ran it wide open so have no idea if it cut the top end. But the low speed manuverability and quick planing were excellent.
