Re: My Gentry build

But if you ever need to remove the tank..... Sooner or later you will.

Since we're talking about custom build boats in our garages, there's really no excuse for not thinking about service and replacement of parts.

Re: Exhaust Routing

If I put the exhaust out the side, I'd be worried about getting fumes into the cabin. Given the main cabin is behind the motor, that is an issue.

If I DID do a side exhaust it would be further back and I'd likely have the same issue anyway, so might as well go right out the transom.

Re: Exhaust Routing

Bob and Thudpucker, thanks for the advice. Good to know it's not that hot. I wouldn't want to char the wood, burn a passenger or do something else horrid to the boat. My desire is to see the inside of the hull skin for cosmetic reasons, really nothing more than that. So trying to keep it clean and n...

Re: Exhaust Routing

:lol: - I had not thought of that! I've been at CAD for years... just takes time. :) Funny though, when I put in the original table of offsets, the numbers Mr. Hacker drew up where off by as much as 1/2". I don't think I saved an original copy of that though... Although - how hot does the exhaust pi...

Re: Exhaust Routing

Somewhere I've seen an inline 'Muffler' wrapped in sound proofing. and some water circulated through the outer skin of the Muffler. Kept the exhaust cooler than the flash temp of wood. It was four feet long and about 10" in diameter. I thought it was ugly and clumsy at the time. Now I'm older and l...

Re: Exhaust Routing

I'm running Pro/E wildfire 4.0. Nice package. I'm at a consumer appliance manufacturer.

I was thinking about that seat, would be nice to have it rotate around. I'll throw up a few more pics later today. Need to do real work now. :)

Re: Exhaust Routing

So I created three exhausts from the Centek range of mufflers. A lift in the engine compartment, a "ski" along the stringer and a horizontal lift in the transom area. Looks like either the lift by the engine or the ski will fit. The ski muffler will need a goosneck and the lift requires the exhaust ...

Re: Exhaust Routing

I'm an engineer and work for a multi-national, so I have "free" access to high end 3D CAD software. Translating a table of offsets into CAD and designing the parts is time consuming but technically trivial. It is a massive help to noodle through problems ( like this ) in CAD 1st. The goose-neck with...

Re: Exhaust Routing

Yes, i suppose they would exit right by the engine. Saves lots of hassle routing. Not sure it's "typical" for a classic runabout though. I've been thinking about style for the boat. Hold to classic bost cues or treat it more like a hot rod. Retro-esq cues, but modern. I guess a side exhaust would be...

Re: Exhaust Routing

Vetus has some nice stuff in their catalog. Are there any internal baffles inside the gooseneck or is it just a compact tube? If it's a compact tube then a 90 > 180 > 90 set of hoses would do the same thing. I imagine that a "gooseneck" with a flapper on the through hull would work great. Just need ...

Re: Exhaust Routing

Yes, the WL is right between the top of the motor stringer and the yellow rib. I'd also like to fit a swim platform on. Some of the ski boats I've been on have the exhaust lower than the WL when the water sacks are filled up and the swim deck is awash. I should probably move the yellow rib down to l...

Exhaust Routing

Wondering what the general guideline is for exhaust routing. (frankly, this falls in the category of mental gymnastics - it will be years before I get around to building this (need to build a detached garage 1st. Long story short, I've had a long term desire to build a runabout. Fell in love with Mr...
