engine weight

I believe it weighs about 460 lbs, but I couldnt verify this on any of Nissan's sites.

My guess is it's more like 315 Lbs. I also could not find any source for the 3.5 weight. dk

Thanks for the information all. I'm hoping it is more like 315 lbs. Thats kind of what I expected and hoped by looking at it. 460 lbs would be too heavy for my use (small boat). I'll try to call up nissan to get a more definitive answer. Hopefully that will turn up a better answer than emailing them did :)

Thanks again, Colin Kenny

If you get an answer let us know. dk

I asked this guy at a repair place close to me (big Nissan guy, just bought a FX over a 350Z), he estimates it to be between 375-400. On a 240SX forum I saw 380.

The first estimate I found from the link below is the engine weight of the VQ35DE. But its from a 2001 Pathfinder, so this may have changed. Also I dont know if that's an official Nissan news site or not.

Thanks again for the info. One question I have about these numbers is what is included in them. Just the engine, or are these weights with fluids, alternator, starter, ps pump, ac compressor, ect. The article that quoted

460 used the phrase "overall engine weight" which makes me wonder if all the accessories were included.

Try to find a car mag review the year the motor was introduced, they usually compare with previous engines and weight is usually included in the discussion. Good luck. Bob

If you offer to buy one from a dealer (retail), I bet they can pin down what it weighs. Can I have a ride in your boat??

Remember that marine engine blocks are different from car blocks... generally thicker, more heavy duty, different cam, etc.

Also, the load on a boat engine is diffferent than from a car. In a car, once you accelarate to cruising speed, you can let off the gas and cruise. In a boat it's a different story because you are 'accelarating' all the time to maintain cruising speed.

Also, if you are cooling using raw water, especially salt, it will eat up your block. Another thing.. marine engines have a multiple drain plugs at the bottom (not freeze plugs). If you live in a cold environment and leave any water in the engine, it WILL crack. I forgot one of the 4 drains on my marine V8 one year and it cracked the block on the side.. had to do a replacement.

I know that's not very technical but it's all I can remember. I have had a few boats with V8 blocks, went the car engine route once or twice, nothing but problems... and a big maintenance hassle.

Good luck!!!!
