Izusu Engine in a Bayliner 2455??????

[JasonB]

Hi all,

My search for a new(used) boat has brought me to a Diesel powered Bayliner 2455 within my budget - Yipee!!!

Of course it couldn't be that simple - It turns out to have a marinised 93 Izusu Trooper Engine in it. Why does it always have to be complicated?????

I posted this question on the PBO forum, does anyone here have thoughts?

All advice, suggestions, rescuing, gratefully received.

Thanks,

J.

I think you'll be in search of trouble. i wouldn't touch it with a barge pole. I

So you finally chucked the LPG in the bin as well then?? /forums/images/graemlins/grin.gif

What's wrong with the Isuzu? It's part of GM. Spares should be easy and reasonably priced as you haven't got the marine supplement to pay.

I have a Yamaha 370 sti in my boat. It's a Toyota bus engine in principle so I can get things like oil filters and stuff without the marine supplement - so I know all about that side of it.

But the engine has been modified for marine use from inception - taking an engine out of a wrecked car and "marinaising" it! Well unless it has been done by a company who knows exactly what they are doing, as I say I'd not touch it with a barge pole! Plese also note that my engine is 3.7 litre turbo, the Volvo mentioned in an earlier post is 170hp. Both engines are significantly more powerfull to cope with the situation.

No, the only person who is going to buy that boat is someone who is new to boating (ergo knows sweet FA) or is never going to exceed 6 knots using it on a river. I wonder if the boat is called "Heath Robinson"?

Yep, I followed the "Solitaire conversion model" almost perfectly /forums/images/graemlins/laugh.gif

Most so-called marine engines are truck engines with cooling gear bolted on so no problem with an ex vehicle conversion. It's naive to think that a converted engine is going to be any worse than a 'marine' version. It's only Volvo who take a prefectly good vehicle engine and [--word removed--] it up to shorten it's life afloat.

 

[neale]

Ah but there are problems with ex vehicle conversions if they haven't been done properly. Marine engines will have components made from different materials and, even though the blocks may be the same, the internal workings will almost certainly have been modified. I wouldn't
say it can't be done, just need to check how it was done and the specifics of that particular engine. Road going vehicles and boats put a very different load on the engine.

 

[alb40]

The components for a 'marine' engine are exactly the same as standard 9 times out of ten. The block are bought from manufacturers as 'industrial engines' and they simply bolt on their gear. Sometimes they play with turbos for extra boost but the rest of the engine is usually exactly the same.

My old boat had a lancing marine engine, the id plates all had 'ford industrial engine' on them even. Exactly the same as an ex car engine, but available with different outputs for different uses by simple limits on their maximum rpm on the injection pump, giving the varying power outputs.

Nothing wrong with a home marinised engine at all IMHO. I had a BMC engine in another old boat, was an ex vehicle motor with second hand marinising bits from jumbles etc bolted on. Worked just fine.

 

[neale]

Yes but an old slow revving BMC in what was probably a displacement boat is a different Kettle compared to sticking a high revving modern engine into a boat which is probably too heavy for it and which requires power enough to plane.

I can assure you that in some modern engines there are many components from gaskets and core plugs to crankshafts and camshafts that are changed, depending upon whether the engine ends up in a car or boat. Thats not to say a car engine won't work in a boat, only that it wasn't designed for it, and when used at its full potential, which this one obviously will be, it may not last as long.

I took a Bedford 466 out of a breakdown truck in a breakers yard. Marinised it and did a round Britain circumnavigation with it and then used for ten years on normal cruising. Eventually sold it to a Nigerian (pre Ebay) who shipped it home and installed it in some huge flying canoe. There is a lot of smoke and mirrors involved in the sales of 'marine' engines. They all go down the production line and simply take a different path depending whether they are going into a dumper truck, or sailing boat, an artic or a power boat.
I'm not talking about the Volvo screamers, but proper engines designed for long life whether in a truck or boat.
