Installed a Raylar 80mm Cool Gap intake along with 1.7 stainless rockers. Reassembled enough to test fire. Still have some wiring and minor adjustments to make. Can't decide to use the stock 75mm tb or upgrade to Raylar's 80mm Accufab tb. TPS and IAC counts look good with.no adjustment. The high pitched whistle when revving is new. Sounded similar to belt squeal but definately coming from the intake. Not really looking for any power or speed gains until I get rid of the stock heads/cam. While apart had the fuel injectors cleaned and flow tested by BUP. Well worth every penny! Also disassembled and stripped all internal paint from the Merc gen 3 cool fuel module. No more problems there. Looks much better I must say..

What did you end up doing to your GEN 3 cool fuel internally to it stripping all the paint out ? Be careful what was used cause of the fuel pumps connections and wiring.
And thanks for the good words in POST # 1.
Also keep in mind those GEN 3 cool fuel assemblies can have up to 3 fuel filters. 2 min fuel filters is the norm but there is 3 in many as well. They need to be changed out once per year min. Best at the start of every boating season.
Also make sure you have the newest basket fuel filter kit. It comes with 2 o rings. The older kit only provided 1 o ring. It needs the 2 o rings changed. FYI to all.

Ryan, when can you run it to let us know the differences?
You only did intake and rockers? What cam? ECU?
FWIW, the whistle will go away if you drill the hole out in the butterfly I think 5/16. Call Larry and ask. I also put a chamfer on mine too and it went away.

I have a Raylar HO525 kit minus the heads on the shelf. I wanted a winter project so added the Cool Gap and rockers. Probably won't add the cam/heads till I pull engine and refresh with forged parts. Stock 496ho cam. PCM has Whipple's stage 2 tune.
I'll look into the tb hole modification. It's stock now. Larry wants me to upgrade to the 80mm tb. I just don't think it's needed with stock cam/heads.

Kept the stock HO throttlebody. Ran the boat this weekend. Lake is flood control and finally at summer pool. Debris still floating so have had to go easy. Got a chance yesterday to run WOT for a min. Hot humid mid 80s, 5 people on board, coolers, 50-70 gal fuel. Very slight chop. Ran 72 @ 4850. Bblades Bravo 1 30p.
Previous setup same conditions would have ran 70-71. Plan on trying my Bravo 28p here soon. Stay tuned

Thanks! Any speed gains will be an added bonus. When the heads/cam are installed is when it will be really noticeable! Pre intake/rockers setup my bblades bravo 28p ran 74 @ 5100 rpms. bravo 30p was 74.7 @ 4875 rpms.
