Engine mounting in a monaco

Postby keith » Thu Dec 04, 2014 5:51 pm

I am about to launch into mounting my engine.

I have a Lexus 4L V8 (1UZFE), with a marine bellhousing and then a 71C transmission.

The engine has a set of mounting points, as does the new bell housing and so does the transmission.

My question is which sets to use. Obviously I need to use the set on the engine, but do I use the bellhousing ones or the transmission one for the rear set.

Pros and cons ?

Keith,

I think I would use the mounts on the transmission. it is a very common setup.
I think a bobtail setup or drive shaft to an outdrive is when the bellhousing mounts would be used.

Thanks for the advice.

So my transmission is second hand and I was looking at the mounting kits the sell at michigan motors http://www.michiganmotorz.com/mounting-velvet-drive-transmissions-p-3111.html. I need the oil cooler as well so seems like a good kit to get. The mounts however don't seem to have any vibration dampening in them. Does anyone have any expereicne with these, or can someone point me towards alternatives ?

The bell housing sold by Cassell Marine, if that's the one you have, is made with jet drives in mind. The Lexus is most commonly used in sprint boats. As Rick said use the transmission pads for the rear mount, otherwise the power plant will be too shortly coupled. Looking at the Michigan Motors illustration is that a rubber bushing at the top and bottom of the stringer part of the mount?

Its a bit of an old post but and update anyway.

I ended up buying the transmission mount kit from michigan motorz. Very good value for money. The following came in the kit

2 x mounts
Oil cooler
2 x oil cooler hoses
4 fittings to screw into the oil cooler and trans to connect the hoses
Gear shift cable quick disconnect linkage
Neutral switch
Temperature switch
Bolts to bolt the transmission to the bell housing
A Clamp mount for the oil cooler
A metal bracket that I cant for the life of me figure out what is for.

The bell housing I have as ozzieboat suggested is from casselmarine, and the lugs on it I referred to I ended up cutting off with the bandsaw because they got in the way.

I just found this site and I think that I may have some engines for your boat builders. Our company does surplus and we currently have several Lexus Marine Engines available. We purchased them direct from Toyota in Asia and we are looking to liquidate them. These engines are the Lexus V8 Marine engines and they are in perfect condition. I can send you photos and any information that you may need.

I am currently looking for the engine for my Monaco. I'm not too good with the Forum strings so I don't see how to get in touch with the supplier of the Lexus engines. Please post that. I'm interested.
