It won't die!!!

[pilty]

It's been abused, shot and neglected but I refuse to let it die! OK, so it's as old as me(39) but, it has life in it yet. What I need to know is how to put the spare 4.0L jeep engine in it. Heather, my partner, is a jeep nut and we just happen to have a spare jeep with most of it's bits. Think I can put the motor from the jeep in the boat? Gonna need some help but I reckon I can do it. I've removed most of the floor cause it was rotten. I have a pretty bare start and need some advice before I begin. Would I be better to put in a floor before or after I install the motor? How do I marinise(englishman with english spelling LoL) the engine?

See the boat at http://www.mypilty.com/theboat.htm

Nope..........

You Can't............ There are No such Parts available.........

Re: It won't die!!!

Then I guess I'll just have to make the parts then huh? I don't really party with "can't do". I need some > "Go for it", and, "This is how I can help"!

Re: It won't die!!!

Bulldung. Maybe you should take a look back in history at how it was done in the olden days. Did you get the name Bond-o from forgetting what nuts and bolts were for? I can put a thermal barrier between the exhausts and the hull if necessary and, use the Jeeps water pump for cooling surely? If my dad could take a 1600cc car motor and install it in a 26' cruiser he built with plywood then, surely it can be done!

Come on man. You know it's possible. Think positively!

Re: It won't die!!!

Is it possible? Probably. Like anything, if you throw enough time, money and effort into it, you can probably make it work. But to what end? Just to say you did? You'd have to fabricate just about everything. You'd be butchering the boat - one that was never designed to support the weight of an amidships motor. There's much more to converting a motor to marine use than adding a thermal barrier to the motor box. You need a marine exhaust header - one that keeps the water from backwashing into your engine. You need a marine starter motor. Marine alternator. These are electrically sealed to prevent explosions.

I'm all for the unique and unusual, but there comes a point where finding a boat that started life as an inboard might be a better starting point...

If you want to take the Jeep theme to your boat, you'd probably have more fun and get more use out of it if you simply redid the hull in a Jeep motif. Some Wrangler decals or Rubicon logos. Throw one of the "Trail Rated" stickers on the windshield. Have some fun with it...

Re: It won't die!!!

boys, boys, behave yourselves. Pilty, there are no ready made parts, for the conversion. no coupling to a drive, sure you could try to use the jeep drive train, a 4 speed on a straight shaft,, with a prop. try to get cooling and seals is going to be a *****. yeah, when i was a kid, dad put a Buick engine and transmission in an old boat. but all i remember it was fast.

 

[pilty]

Re: It won't die!!!

Backwash? Scott seems to have some idea of where I'm coming from.

The hull will support the motor and, I think, if I get the center of gravity right then, it should work. As for your comments Bondo-0, yes that was a zero. Just because I have no job(thanks to your countries immigration red tape) and, no money, doesn't mean that I have no resources. (EDIT: Deleted pesonal insult. JB)

Scott I would love to hear more of your thoughts on the project please.

 

[pilty]

Re: It won't die!!!

Hoorah for Tashasdaddy!!!!!! I know it can be done cause MY daddy did ot too and that was fast also. I'm getting tired of can't do people. I know it CAN be done and I'm gonna do it so, stop with the CAN"T please people and help me with the CAN!

 

[pilty]

Re: It won't die!!!

So if I put the whole tranny and engine in I take it that I will need a stern gland for the drive but, I can straight pipe the exhaust over the stern? Use the Jeep motors water pump for cooling?

Re: It won't die!!!

C'mon guys! There's no need to start hurling 3rd grade insults at each other. We all come here to learn, for our selves and from others mistakes and truimphs.

Just becuase you "can" doesn't always mean you "should". Although, I can whole heartedly understand the hatred for the "can't" mentality. I don't think that it is ALWAYS wrong. Sure if you want to do it, go for it. The old saying goes: "where there's a will there's a way".

Just remember you came here asking for help.:/ Most of the guys here have been there done that, and are only trying to help you out and to succeed.

Keep us posted on your decision.

Best of luck,
Lowell

Re: It won't die!!!

You'll need to route every engine vent out to an external hull vent too. This includes crankcase vents, fuel overflow vents, etc. Basically anyplace the system attempts to breathe. You'll need to do the same thing on the vacuum side too any input needs to come from outside the hull. Remember, a car's hood breathes all around. A boat hull breathes just about nowhere. Recirculating an engine's fumes can be a recipe for a giant fireworks show at your expense.

For exhaust you could probably get away with a set of ceramic-coated headers. That'll set you back some actual $$ though. Those you can wrap your hand around while the engine is running and not get burned. Anything else would need to be water-jacketed or you'll be melting or burning your boat away.

It CAN be done. But, you'd probably be better off spending 1/10 of the time it's going to take looking for someone with a marine motor that wants a jeep motor and simply swapping.

Re: It won't die!!!

Okay - keep in mind the boat looks to be about 17-feet long. You want to use the Jeep engine - straight six? Plus the automotive tranny? You're talking about 7-feet of cast iron - in the middle of the boat, if not a bit forward of that. You have to keep the angle of the propshaft modest, otherwise the prop will just push up the back of the boat, and won't push you forward. And you would likely need the prop to extend no further than the transom, as you could add a rudder flush with the transom. So you've got about 4-5 feet of propshaft, plus 7-feet of motor and transmission - that puts your center of gravity forward of the center of the boat. In a boat made to carry the weight in the stern, this is a major problem. This is why a compact marine transmission that only takes up a couple feet at most is the way to go. You could try a V-drive, but that would be another whole can of worms, as you're probably not going to engineer one from scratch, which means adapting one to fit. Not a job I'd be looking forward to...

As mentioned before - I'd go for the "look" of a Jeep, rather than the guts... You could even toss the plexi windshield and bolt on a real Jeep fold-down windshield! Maybe adapt a Jeep convertible top, too! Add some Jeep bucket seats, steering wheel, dash gauges, etc. Could look trick!

Re: It won't die!!!

I have a boat with a motor that's gonna cost me more than I have to fix. I don't have a lot of options. Yes, I did come here to ask for help. I am beholden but, I need cans not cannots!

Take a look at the boat and motor and help me get it afloat with at least a reasonable amount of speed safely.

Re: It won't die!!!

If it were me, I'd disassemble and part out the motor you have on ebay. You'll be surprised how much you'll be able to get for the bits and pieces. I don't know what that jeep motor is worth, but see what you can get for that too. Use what you make and try and find another complete outboard in reasonable shape. You'll be surprised at what you can find for under $1000 if you look hard. I'd think you should be able to come up with that easily by selling what you've got.

 

[pilty]

Re: It won't die!!!

That sounds like my next move iwombat. Thanks for a good tip. I'll see what I can accomplish that way. I'd rather fix the motot tha oiece it out but it seems like that is the only option left. The compression is good and I'm pretty sure it only needs a powerpack. Sad end to what was probably a very good motor!

 

[OhioLowell]

Re: It won't die!!!

Will the cost of a new or used powerpack out pace the cost of another motor? I don't know but I'd look into that too.

Re: It won't die!!!

If it's just a powerpack, part out the spare jeep you've got and use it to fund your boat.

Spares are worth absolutely nothing until you use them, or sell them.
