Or buy and eat the 15 McDonalds meals. Let M drive the boat ,you sit up in the V berth. With the weight you gain from all that fat and empty calories you will bring the bow down!

After reading all the posts, I think I am sold on adding the Permatrim to our Honda BF75. What is the supplier everyone is using?

Instead of buying the permatrim go look at( Bobs speed shop )the stabilizer plate does the same thing as the permatrim but is only $60 and is made in america We used one on our cd-22 look in our duck folder

Go look at Marc's (wefings) remarks about wedges

One thing to remember is that the permatrims should run on the surface of the water at speed, not below the surface. I have never used the "Bob's Machine Shop" fins, but they do make good products, and I am considering one of their jack plates for the Caracal.

Thanks again. I'll look into the American made stabilizer plate.

I think I might need a Permatrim for my 16 Angler. Even on virtually flat water I find that I really can't run faster than appx. 16-17 mph. or the boat starts to porpoise. With hard acceleration and the new engine (Honda 50 EFI) the boat almost seems to leap out of the water, then bangs hard on re-entering the water. I somehow need to get the bow down and the boat running more level. Does anyone here have experience with Permatrims on a CD 16? Any input and/or suggestions would be greatly appreciated. Thanks, Mike.

You might want to consider trim tabs on the 16. Also check the balance of the load. A boat which porpoises is often out of balance, or there is a hook in the bottom etc. That type of handling can be dangerous--and is not at all normal.

Steady Eddy,

I had a 40 HP engine on a CD 16 Cruiser, which is more stern-heavy than an Angler, and could easily get up to speeds of 21 to 26 MPH, depending on the direction of the current. You start with setting the trim angle so that the bow is down, and then adjust trim upwards to an optimal angle as you go on plane. If you are leaping out of the water, you probably have the bow angle set too high, and are applying way too much initial power. Either that, or you have so much weight at the stern of your 16 that you are stern heavy. If that is the case, it would be helpful to move more weight toward the bow. From what people have said on this website, Permatrim should get you out of the hole quicker, and more easily keep down your bow -- particularly at slow speeds. Unfortunately, I had a Suzuki, and putting on any hydrofoil on a Suzuki invalidates the motor's warranty. Other manufacturers like Honda don't mind, and they even market their own hydrofoil.

Check where the motor support is in the brackets. It should be in the position that has the motor all the way against (as much as possible) the transom. I believe it will be the lowest position. (keeping the bow down, you can always tilt the motor up but not down past the pin)

Easy to adjust (at least it was on my 45's on my 22) just tilt motor up, straighten the toggle at the end of the pin, slide it out and move it in the direction you need to. Be careful if you're in the water however, they are not known to float... Cry

Don't ask me how I know that... Embarrased

Thanks for the suggestions you guys, I appreciate the input. I called Honda today and they confirmed that adding a hydrofoil like a Permatrim is fine for warranty purposes. I also spoke with the engine rigger, who said that a 4 blade prop might help a bit to keep the bow down. Since I'm still dialing in the prop I might choose a 4 blade model just to see if that makes a difference. The tech I spoke with at Kruger Propeller also suggested trim tabs. I may be mistaken, but I didn't notice a set pin for adjusting motor down trim range; this may be a change made by Honda when the new model came out a few years back. I will make a conscious effort to move cargo and people forward and accelerate more gradually; we do this when commuting to the island and I do notice the difference. I really like this little boat, but I can see why a fellow brat (Oldgrowth I think) added a few feet and shifted tankage forward. I never did hear his feedback re: how his boat handles post-modification. Take care, Mike.
