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..

That looks very , very bad azz.

Now you have a table on your boat

I'm happy with how it turned out and yes it works great to sit your beer on!!!

I'm not sure how safe it is to drink beer while operating a water vessel. Just kidding, engine looks great. I'm sure when you upgrade the heads/cam it's going to sound even better than it looks. Cheers

It looks great Ryan. I'm looking forward to seeing, in a few months, the results of the water test.

Nice work Ryan... looks killer! Sounds damn good as well!!!

I'd still like to cut your old one apart to see how easy it would be to produce a better one

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.

The air comes in at the bottom of the intake and then upward thru the runners. GM designed for long runners that did not need alot of extra height for the applications being used in. That was their ( GM ) main objective.

Correct ----- Stock --- was a 75 mm bore size for the the throttle body. Id see about 80 mm bore.
