I was hoping to find some Merc 575SC tops complete with blowers & throttle bodies. None seem to be moving around. May look for some whplles or go bigger

Plane Silly,

Sorry Rage, I don't know what size they are it was installed when I bought the boat. If I where to guess I would say 3/8 ID.

Hey Plane Silly, thanks for your help.

I used 3/4 inch lines on my oil cooler and thermostat. The cooler didn't have a built-in thermostat so I used a Hardin Marine billet filter block/thermostat. The set-up worked really well, but spent a fortune on Russell hoses and fittings to make it look pretty!

heres a chart

looks like #6 could be #8, I use #10 boat and cars

Well you accomplished your goal of making it look real nice.

Good looking engine. I could open the candsspecialties.com url but the holly.com url would not open.

In your picture showing your oil cooler, are the 90* angle water fittings 1" NPT/1 1/4" hose nipple? If yes where did you get them?

Plane Silly, Your oil cooler is held down by what appears to be typical T bolt hose clamps but there is also some sort of plate as well that is bolted/screwed to the floor which is mostly obscured by the cooler. Any idea what this floor mount hold down assembly is comprised of and where it can be purchased?

Thanks for all your help.

Bill

Sorry I can't help much with the mount. The Tbolt clamps are made to the floor mounts. I'm sure CPperformance or Eddie Marine carry something like them.
