I'm looking at buying an old fishing boat which would best be described as a 'unique fixer upper' (read; piece of sh!t).
It runs a 4 cyl, Vauxhall marine engine, that, mainly because of its height, makes the cabin unusable. So it has to go.
My thought is to drop a 1300 upright into it.
a) because I have one on hand.
b) because it is a, dimension wise, a smaller engine, with roughly the same horses.
Like most of my ideas, I know what I want to do, but don't have the faintest clue HOW I'm gunna do it.
If someone else has done this I would love to hear from them.
If this is a first, then no idea can be a bad one.
My main concern is the heat of a VW motor 6" off a wooden hull.
Well my friends are gone & my hair is grey, I ache in the places where I used to play.
how are you planning on "mounting it"??
Should think some cement fibre board would take away any heat issues
An guessing th Vaux exhausts into the water for noise?? - so a custom exhaust shouldnt be that hard
As long as the air path isnt blocked - "should" work
Wouldnt plan on skiing behind it though :thumb
Futue te ipsum!!!
Volkswagen did it with 36 horse engines....
Thanks Matt.
Seeing it done sheds a lot of light on the subject.
Wonder where I can lay my hands on one of those gearboxes.
Well my friends are gone & my hair is grey, I ache in the places where I used to play.
There must also be a second box or at least a transfer case as the 'box' faces the front of the boat...
what do you reckon the jacket things on the heater boxes are???
Futue te ipsum!!!
As long as you can keep it cool don't see a problem. One consideration is petrol and inboard engines can be a concern although there's plenty of them around.
If heights the issue try a type 3
I'd say that they're air ducts, as they cover most of the bottom of the engine (Under the cooling fins). This could be your answer on how to solve heat issues, 'duct the fuct air'.

Those jackets exit the hot air out through the transom along with the exhaust by the looks. That way your exhaust heat is removed as well...clever idea
It's quite ingenius.Yu could still place heat resistant insulation over the timber, just in case. Looking at this makes me want to get an old hull and Buggerise it. Pitty mum would kill me if I did.

As I said, I have a micky mouse upright on hand.
There is a gearbox on the vauxhall now, but, although there are adaptors to put just about anything on a dub box, I don't know of something to go the other way.

normally inboards run risers with water being introduced into the exhaust to keep it cool. you may find the ducts in the photo incorprate water for cooling the exhaust which exits through the transom. this could be done by water jacketting, or simply by introducing the water straight into the exhaust provided it is uphill of the exhaust outlet.

I forgot. the gearbox prob. depends if the box you currently have is a direct drive either through the transom or mid mounted with a shaft drive, or a v-drive like the one in the picture and most ski boats. you may not need anything except replacing the engine just depends on what you got already.

you could use a dub gear box and run the axles out through the side of the hull and hook up some paddle wheels.
Sorry
Pump and drill output gearboxes are available for VW engines...
One of those could be adapted for the screw if an adapter could not be fabricated for your gearbox...
Let's get something straight.
The only nautical term I know is hull.
Short of that I know absolutely f#ck all about boats, other than the pointy bit is the front & when you put it on the big blue wet thing, it's meant to float.
What I do know;
It's a 21' clinker, 3/4 cab, but the hull has been 'glassed'.
The motor looks to be pretty much dead centre (both ways).
The exhaust does come straight out the back & appears it would be under the water line at all times. Right now it is on blocks.
(I have tried to put a pic up but I can't make it work)
The price is right, & I am assured the it will work as is.
The worst that can happen is we have an $800 bonfire & sausage sizzle at my place
:P
Well my friends are gone & my hair is grey, I ache in the places where I used to play.
that old pic of the vw engine would run into a V drive very common use with inboard engines and a bit price
V is how it sounds box runs into it the the prop sharft runs out on and angle

bwaaahahahahahahahahahaha good one.
My father in law used to run a weird looking boat with a car engine in it.
He simply adapted an old Holden 3 speed to the engine.
Just uses reverse and whatever gear ( 1 or 2) that worked for his prop. Easy!
If the engine drives the wrong way, why dont you just turn it around and drive from the other end?
Dun matter which end you drive from.

I would hazard a guess and say they were water cooled jackets on the heater boxes..:o
As for engines...I would recomend forgetting about petrol and look at diesel....much safer and more economical...I would look at a Golf diesel setup...actually there was a mob that did a marinised setup of a golf engine for yachts......think they traded under name of "Peter" or "Peta" engines....if I get down to the club this weekend I will ask some of the "old salts" and report back.
I dunno.
Why, all of a sudden, would you need to cool the exaust? No vehicle any one of us drives needs it.
My suggestion is, that it is exactly what I was asking about in the begining, a barrier between the exhaust & the hull. It's just a cover the same principle you see on any Mack truck.
Look where it is part of the tinware.
The tinware on your air cooled car directs the air from the fan around various parts & vents to atmosphere under the car. I think this is just tinware to direct the hot air straight out the back.
The reason for the petrol motor, is as I've said. Because I've got one. No further expense to the management.
Well my friends are gone & my hair is grey, I ache in the places where I used to play.
i think they cool the exhaust because the engine is enclosed hence limited air flow. so they rig a seawater inlet and use the forward motion of the boat to supply the flow of liquid to cool the exhaust which then flows out the back of the boat
“We all pay for life with death, so everything in between should be free.” Bill Hicks
the chaos project - click me
The engine is enclosed on a kombi & half your exhaust is enclosed in the heater box.
I just can't see why you would need to cool the pipes on this, but no other time.nn[ Edited on 18-8-2005 by Spook ]

Anyone watch Jaws the other night? That boat style above is a ringer for the one Richard Dreyfus pulls the shark tooth from the hole in the bottom and the severed head falls out. Classic piece of cinema!
the exhaust needs to be cooled generally in in-boards because the engine runs at a higher loading, as in the engine works a shit harder because of the resistance of the water. There's no stop and start, its all go-go-go-go in a boat and generally at higher revs than in a car. we've all seen cars on dynos run, after a while the exhaust gets hot and starts to glow, and thats not on performance cars....
To live and love is a gift, to video tape it and get caught is stupidity
Besides having their exhaust pipes water cooled most inboard marine engines also have their exhaust manifolds water cooled.....I have also been told that the intake manifolds on some petrol inboard engines are also water cooled. Many a inboard petrol engine has taken the boat & passengers to Davey Jones locker.

hey doublecab did you get info on marinising the golf diesel...I'm looking for info on this?
But I'd probably agree - more economical and less volatile than petrol..
I'm not talking about a speedboat here.
This is a 50 year old(at least) wooden lake boat. This is not designed for speed or open sea. Just to casually stroll around the lake.
Other boats around the same age that are moored around here are one or 2 cylinder air cooled engines.
I was talking to a bloke Sunday at the jetty here. His boat runs a single cylinder, air cooled. It sat pretty much in the centre of the boat with a box around it & the exhaust just came straight up & out. No marinisation involved.
As he left the jetty, it never got above an idle.
A 1300 in much the same sort of boat, theoretically, should never really have to work hard, so shouldn't need 'extra' cooling.
The petrol versus deisel, I think is a mute point. This thing has had a petrol motor for 50 years & still exists.
Half the people you see on the news when a boat burns will tell you they could smell the fumes but fired it up anyway.

Motors were originally marinised by a Co called "PETTER" who now are called PETTER/LISTER and I have been told all their marine engines are now Lister based....they have a website and Aussie agents.
My local marine man is Peter of Belco Engineering and he tells me that one could/would be able to source the major parts (intake & exhaust manifolds & water pump)required to do the job.... he also told me he knew where there was a recently reco ed engine available.
If U are interested U can get in touch with Peter (for parts info etc)via
belcoengineering@bigpond.com and tell him Leo gave U the contact info.
