Jeepers Paul, how do you do those diagrams?  Some kind of fancy computer program?

Absolutely the wrong prop and not doing his motor any favors topping out at 5300 rpm-what is he running a 21"?



Fletch has a 23 jumbo and 140 suzi.   He wishes more speed getting only top end of about 24 mph he told me. And like 5300.   Could it be the wrong prop?

Ditto on the concurrence with the previous posts.  

Another option is XPS foam, which is the Dow Blue Board, Owens Corning Pink Board, etc.  Not the white stuff.  I used this as a support for the deck, so it doubles as a structural component as well as flotation.  But you can't use it in a fuel compartment, as it will dissolve if exposed to any organic solvent such as gasoline.  

The polyethylene foam is OK for use in a fuel compartment, as it is impervious to organic solvent attack.  Same stuff the fuel tank is made from.

Here's a cross section of how I did it under the deck.

I stuffed some in the bow as well.

Positive flotation and a self bailing deck are must haves for my boat.

When I launched 6 years ago I got a AGM from West marine for starting battery.  Spendy but still gong strong.  I have gone through 2 regular batteries for the house battery.  This year a bought an AGM from Cabelas for the house battery.  Either one is plenty large for starting.  They are in the cabin near the door.  I went AGM for less Outgassing. The only connection between thr 2 is an ACR.  Works well so far.

Sorry to hear that you have to sell. I hope you can figure out a way to keep it, but I am interested in talkling to you and possibly buying. I know of a trailer manufacturer in that area. I want to build a 28 and was trying to decide between GA or stretched Jumbo. Please pm me when you are ready.

Max RPM on the suzi 140 is 5600-6200 on the suzi website.

he definitely has the wrong prop, engine height will enter in also, but the prop has more influence. If the engine height is way deep then move the engine first test again and then choose a prop to switch.


Cheers,
Jerry

I concur with everybody and wanted to say ditto on CraigF's post.  The key is polyethylene.  Ends in 'ETHYLENE' ...I've tested different closed cell plastics before and the one that lasted perpetually and seemed the most bullet proof to things like rot was polyethylene closed-cell foam ...you can buy it in sheets and cut it to fit.  If putting it under deck or other places where water can get trapped, it's not a bad idea to at least put some runners under the foam so water can more easily drain down and aft and out...

This is a really useful posting as I have been thinking about this to.
One of the ideas I have had was putting lots of old fizzy drink bottles under the deck, eco and in theory, "floaty", technical word.

I wonder if these would rattle around?

Those Toyota diesels are awesome. But short of importing one at prohibitive cost, North Americans can only read about them. As fuel prices climb, maybe that will change.
