From all the reading I've done, it looks like intercooler, cooling system upgrade and spark arrestor removal are kinda like a package deal.
Intercooler upgrade is the key, no doubt. This should be a warranty fix if you ask me.
I did do the ribbon delete along with installing the Frozen boost brand intercooler along with taping the pump housing strainer plate for the stand alone cooling feed line to the intercooler and these 3 things will make you 192 run like mine. The frozen boost cooler is the type 14 model.
Yes your right the SVHO intercooler will do the job, it should have been installed from the factory on the 192 models. This is an expensive intercooler from the yamaha parts department so thats why most of us have gone the Frozen boost way. Frozen boost type 14 is about $150 plus about $100 in elbows and pipe plus clamps. You can do the whole job for $500 bucks complete.
Do you also have the ribbon delete? If so did you do the intercooler upgrade at the same time you removed the ribbon? I'm trying to determine if removing the spark arrestor is need as I'd rather not take apart all that if I can get the same performance you got. Sounds like exactly all I'm asking for this boat is perform like yours does now.
I think the filter would work better if it had been placed closer to a cooler air source, its hard to say how restrictive it really is, I removed mine altogether.
Yep, thats the one. I did the ribbon delete the same time as the intercooler, I think it helps out of the hole but top speed would most likely be the same with or without. I think its worth doing it. The ribbon delete isn't to difficult, there is plenty of room to get to everything.
Yes it will fit no problem, I machined the center of my plate to eliminate the x pattern then taped a brass elbow into it.
It would be a direct swap but you would add an extra water pisser to the side of the boat next to the other 2. 1 of the reasons the pump strainer plate is taped for the extra water supply is so the new intercooler has its own water supply and not having to share the same water supply line that feeds the engine cooling( like the stock set up). The jet pump forces tons of water into that strainer area so you would never have to worry about taking cooling water from the engine.
Yes, the x is the casting on the out side of the plate held on by 4 bolts, you have to machine it flat to make taping the brass fitting eaiser. Or purchase the Riva racing performance cooling kit. The line goes thru the hull via. thru hull fitting and directly to the intercooler
Ok I just went out to my boat to have a look and I see the x pattern on the block that would need to be machined. I think I'd rather just buy the RIVA kit though in case I need to return it to stock for whatever reason. I didn't realize we would need to drill into the hull for the thru hull fitting, I will need to prepare myself mentally for doing that on my brand new boat haha. Do you have a part number for the RIVA strainer kit?
Sorry I don't , Green Hulk should have the kit listed. I know it sucks to drill holes in new fiberglass but in the end you will be glad you did it.
