has anyone switched to multi-vis CAT (or other) oil yet? Any difference in performance, samples, etc.? Ours has the T1 in it from the fall change and I'm still contemplating whether to run a season or switch out after we launch to the now CAT recommended DEO
I switched to the CAT 15/40 for my fall oil change.
not many hours on it I’m assuming? Since you’re in Michigan
On that surging - there are five tiny plastic check valves in the injector pump. Over time they tend to get gummed up and will not check fuel flow causing a surging / unstable idle condition. They are cheap and easy to replace.I believe about 1 hour run time since the oil change. I know that the previous owner used 15/40 for years in these engines and I was the one to change it to straight weight. I have nothing to base this off of besides feel and sound, but I feel like the boat runs better with the 15/40. I had a port engine idle surge after warming up that nobody could diagnose, at least the last run of the year it did not surge.

This shows 4 check valves but I'm pretty sure there are 5 in the system.I’ve read this mentioned many times here and on other sites, I think it should probably be baselined our engines since the previous owner was a bit loose with fuel management
I’ll take a look through the service manual, are there any other resources you’re aware of that show the process? Hopefully they’re easy to access

In the process of slowly painting the whole engine bay. First is a degreaser, then a spinning brush with Total Boat Dewaxer. Have retained Andy Miller from BoatworksToday.com to provide technical assistance with the refit. His input has been invaluable.Be careful repainting the bilge floor on a Sea Ray with a little age on it: Sea ray uses a gelcoat (not paint) called gray bilge coat. It has a wax component in it that comes to t he surface when the hardner kicks in the gelcoat. That gives you a bilge surface that is impervious to oil spills but is also one that requires a lot of sanding and acetone to get a paint to stick to it. It is going to be a much harder job that takes a lot more time than you would ever think.
Andy is AWSOME!! I love watching him work, and I've learned a S**T ton from him. One of the few YT channels I actually subscribe to. I imagine he'll be a big help on the swim platform. Did he recommend the structural material for that rebuild?In the process of slowly painting the whole engine bay. First is a degreaser, then a spinning brush with Total Boat Dewaxer.

The question is, where are these little buggers actually on the engine? I've never seen a picture or well documented how to on these. I have the CAT service manuals, but haven't come across this there either.This shows 4 check valves but I'm pretty sure there are 5 in the system.
All but one are on fittings and plugs on the pump. For example the fitting the tube connects from the fuel filter is one and the little screen filter. My mechanic changed all on my engines and it took him about two hours to do all.The question is, where are these little buggers actually on the engine?
