Thinking of switching from Valvoline Blue to Shell Rotella this year. What are you guys using T4 or T5?

T4

Read somewhere that fully synthetic was no bueno so didn't consider T5 either.

Good luck,

T4, usually get it from Tractor Supply $94.00 for a 5 gallon bucket.

Both Rotella T-5 and Rotella T-6 15w-40 are on Cummins approval list for CES 20086 oils. Cummins does recommend against extending oil change intervals with synthetic oils. Cummins recommends the use of CES 20086 oils anywhere that CES 20081 was specified previously.

I can't see where to start a new post so, does anyone know the Sherwood part number for the raw water pump on a QSC-500? TIA

I’m getting my winterizing bucket set up and won’t be able to get to the boat for a few days. Does anyone know the size of the raw water pump intake hose? I’m just going to next my bucket directly to the pump. Thanks.

I think it’s 2 inches. I use the Trac Eco Sea Flush with the snorkel. Very easy to use, cheap and has how to videos on YouTube.

The hose on my QSC 600 is 2.5 inches.

I also use the Sea Flush. Works awesome with the snorkel attachment. I run 15 gallons through the engine. I set up 2 5 gallon pails full of AF, and transfer the snorkel between them. Stop the engine, refill 1 pail, restart and it's done. Filling the buckets takes longer than running the AF through the system.
