I'yard not certain which years or applications are considered the second gen... only I'chiliad enlightened of some differences on later model Weber engines later the '04 MSX 110s & 150s.

The Nicasil plating process was improved and made more reliable... less plating failure problems.

The waterpump was redesigned. It now used a plastic impeller in the waterpump and housing was revised to include a built in piping that continued to the coolant rails on the intake side of the block. The 1st gen used a rubber hose. The gears that bulldoze the waterpump (weigh shaft, bulldoze gear, waterpump shaft gear) were revised and were now all metal... removing troublesome plastic drive gear from the 1st gen.

The oil tank was redesigned. The old heavy metal tank was redone in lighter plastic. It removed the divide oil separator whirlwind and congenital information technology into the top of the tank. It besides removed the loftier pressure valve that opened the tank to atmosphere when the engine was running (worked off oil pressure line). Information technology as well added a secondary tank on the side of the oil tank called the rollover tank which helped forestall oil ingestion in the event of a rollover.

The oil filter housing is metal on the snowmobiles... plastic on the MSXs... non sure of other applications.

The pistons and rods used in the Polaris FST snowmobiles are slightly dissimilar (beefier?) than the MSX watercraft version. Not sure if this became norm for all the Weber engine variations.

In some applications the engine was cooled via open-loop fresh water organisation... no closed-loop cooling system similar the MSXs. The Hydrospaces were similar this to cut down on weight.

I retrieve the MSXs were the just ones to use throttle past wire with an electric throttle torso. I believe the other applications used a throttle connected to the throttle body.

In some application the magneto system was replaced with an external alternator... in the snowmobiles for case.

The intercoolers were different in different applications.

The ECU and engine direction organization where different in different applications. Bosch vs Walbro vs ???

The frazzle outlet off the turbo came in a longer version (like the MSXs) and a shorter version... for dissimilar applications.

That's all I tin think of.
Thank you!

What are the upgrades offered? Water pump, oil pump, and tank correct? We are at the betoken where I take three of these motors set up for rebuild. Nikasil failure in all of them seems to be the culprit.
