air craft motors and air shrouds

Just wondering if they work all that well, and if they were worth the effort. Have never actually seen one on a boat, just photos.
 
mwood, I put one on a 125 lycoming that overheated constantly years ago and it cured it right up. Built it out of 1/8" aluminum and it bolted up around the rocker covers. It was about an inch above the front of the motor and curved up about eight inchs at the back.
 
Yes they work and are worth the time and money. Bobby Corey has one on his 520 and we both run all day side by side. We both are running 520's and my temp was 175-185 while his was 140-145. Both boats loaded the same( Except one of my passengers was wearing a micro mini skirt). Robert Carlton built the shroud and it is also great looking. The price is about 800.00, last time I was told. Thats cheaper than replaceing cylinders.
 
My interest is purely technical you understand, but WHERE do I get one of those micro-mini skirts for my ride boat?


Scotty :D
 
BigDaddy, if they ever put the scent of burned LL100 in a bottle I'd have a new favorite aftershave :lol:
 
Robert Anderson vero beach 772-633-2450 fiberglass or metal he made mine and it works great. If that number is wrong I can try to get the another but I think it works.
 
The price is 450.00 from Robert Anderson and he will ship. I just called him to confirm the price. I hope this helps
 
Hey folks;
I made a cooling shroud for my 220 gpu for about $20. I made a skeleton type frame out of 3/8" re-bar (yes, re-bar) and covered it with rubber roofing material.
The rubber is pulled tight on the sides with springs and eyelets and tie wraps and eyelets on front and rear.
I cut a square hole in the rubber just big enough for the intake to poke through and then re-installed the carb (holley).
The frame is about 1" above the jugs in front and about 18" high in the rear. Ther are 6 runners running front to back equally spaced side to side for the rubber to lay across.
The frame extends back to within a 1/4" of the prop, and when I rev it up you can see the rubber suck down tight to the frame creating a monsterous flow across and up through the jugs.
My engine is older and used to heat up easily, I've been running this set-up for 10 yrs. and can run all day and not overheat.

just my .02...Jim J
