Does anyone know the weight of the engine, with and without the gearbox?
Thanks, Rob

I seem to remember 274 lbs. for the engine, but I am not 100% sure.

Heavy and even heavier would be my guess!! :lol:

Sorry, I have no idea, but it would need two people to lift it safely..

The service manual says 260.4 lbs dry weight. As its once case there is no weight listed for the gearbox.

Thanks Ernest,
That is heavy even if it includes the gearbox and clutch. Could you confirm that the 260lbs includes the whole engine, clutch and gearbox. Normal Honda design it is all in one case so I expect it is.
I am thinking of it for an aircraft; better replacement for a VW engine. But it would be sad to buy the whole unit and then chop of the gearbox. That would probably be about the same weight as my current 2.4L engine so not obvioulsy a good route.

Thanks for looking it up,
Rob

I couldn't find any other weight listings and yes its all in the same case, I think the gearbox is the smallest part of the case as the shafts are stacked.

I don't know anything about building aircraft but wouldn't something air cooled be better? A cooling system would add alot more weight.

A few people have looked at the Goldwing horizontally-opposed engine and thought; "airplane engine!" Every time this topic comes up, the person considering it abandons the idea because of the size and weight of the transmission. It's not a simple thing to just "chop off" the transmission, as it is below the engine, integral to the case, and lots of things such as oil pumps, the water pump, etc. are down there as well.

Could you do it? Sure, if you have unlimited time and money. But after the expense involved in modifying it, you're probably better off just buying a Rotax or IO-360.

Thanks Ernest and WingAdmin,

Yes, I am afraid I must come to that conclusion as well. Just too hard to convert to an aircraft and "chop off" the gearbox. I have an aircooled purpose designed aircraft engine. It is OK but has overheating problems, life problems, starting problems, and expensive etc. Why, because the aircraft manufacturers only do a few hundred engines, they are old tech and just don't have the resources of Honda. But it is probably better I concentrate on it and solves its problems as they occur.

I was just hoping for a perfectly designed modern engine. Was hoping the gearbox was bolt on. Also I listened to my old CBX 6 cylinder the other day and I get goose bumps it sounds so good!

Have fun,
Rob
