Great post! Interesting or are the Yamaha non power valve 1200 could weigh 20 lbs more than the 1100 when the smaller motor has the entire lectronics attach to the front of it. I would think those numbers are backwards?

I believe the 65u 1200 non pv weight includes the Ebox. That ebox is heavier than the 63m stuff that's built into the stator cover

Here is an updated version of the original post: https://business.facebook.com/Minije...00486576651023

Common donors and their weight in pounds.
We weigh these motors as complete as possible with exhaust, intercooler, supercharger, ecu and as many bolt on components as possible.

Weights do not include any pump or driveshaft components.

If the line has a dash (-) then weight was provided by a 3rd party and may include or exclude additional components.

If you have some weights of other engines let us know.

Actually the 15F engine only weights 177.2 lbs

The watercraft Journal says the Kawi 1500 is 202lbs... which is closer to the 197lbs posted in the thread. I think your scale is optmistic

I guess you can't believe everything you read. Scale tested out perfect. I just weighed the engine, exhaust, and intake I'm sure if you put motor mounts, ecu, and wiring it probably weighs 197 lbs. I don't feel that other stuff should be included if you're looking for the engine weight just my opinion.

- 15F engine - 177.2 lbs -

About a 10% difference.
What might account for (some of) a 20-ish pound difference in measured weights?

Engine electrical components included in some weight measurements?

Some engines may have the oil drained and filter removed, some may not? (About 8 pounds for a US gallon of engine oil)

Driveline coupler removed vs. present?

[stephenspann27]

That same watercraft journal article lists the TR-1 as 124lbs... and elsewhere on the internet it's listed as 160lbs. I wish the details of how they are weighed were listed.
