Boats MUST LIST A LOCATION (State)IN THE TITLE (Seems people can't read lately)-along with Make/Model/Year
It will let the engine breathe better, maybe a 200rpm top end increase.
So worth it or not?
It is a must do in N/A 1.8s. In SC it is more of a project and the gains may not be tangible.
Cool thanks for the honest feedback
RIVA racing, or order from greenhulk (with 10% discount blah blah), but make sure you specify exact the model - check the part number for your MY 1.8. Yamaha has changed the intake manifolds back and forth, it is impossible to keep track, and there are two different sizes.
Yeah I’ve tried to figure it out as well, I’m not so sure there is a “system” to it. I think Yamaha just randomly pulled parts off shelves when building engines. lol
I like this for searching parts (they also have very good app)
On my 192 the biggest difference I could tell was increased throttle response and my RPM's were a hair higher. Top speed was unaffected. Engine will sound a little throatier. It's kind of a chore to swap out the ribbon on a SC boat because it's down at the bottom of the engine where the throttle body is. You have to remove the intake manifold in order to remove the throttle body in order to remove the ribbon, so yea it's kind of a pita. Was it worth it? Eh, I don't think so for the SC boats considering how much I bitched along the way during the install. The N/A boats seem to respond better to the ribbon delete than the SC boats. In hindsight I probably would have removed the intercooler as well since it opens up some room to work. Stuffing your arms down in the bottom of the engine isn't fun unless you're a smaller guy or have super long arms then maybe not an issue. I had bruises on my chest for a week because of laying across the engine for so long
