Left one came off of a late 90’s 583 I picked up off eBay. I bought the block off and removed the oil setup. Problem is that setup and the connecting boots put the carbs right on top of the trans with no room for an air cleaner. So I pulled the original one of the old bad crank Engine. The old carbs were junk and the new carbs are 40’s not 39’s so I’m waiting on new mikuni carb mounts. The RV cover on the right is from a early 70’s Blizzard 7500/9500 model sled. I couldn’t find anything on it so I joined a group on fb and have been asking questions. This setup lets me keep normal carbs (which I like better) and moved them about 3 1/2” away from the trans. There are 2 styles to that RV cover. One is flat and the other is angled to help the carbs sit flat. They are few and far between though as I’ve only seen one of the angles covers.
The Briggs rusty put the 583 in has the watercraft carbs and changing jets is going to suck for a minute or two. He made me a set of braces to help support the weight of the carbs.
Have you tried fitting the shorty cover on? I have one from a sea doo without an oil pump, the bolt pattern is off so it would not work but also it would not go all the way in due to the length of the RV spline that is setup for driving the pump, was wondering if that cover would have enough clearance?
