Looking for any info on changing blocked exhaust manifold for Universal 5411 (salt water cooled 11 HP). Also, any thoughts or experience with installing an aftermarket fresh water cooled system?
I had a overheating problem in my 28 and after much searching foud the tube that is welded into the exhuast pipe had slag in it and would stop up with carbon after drilling it out I have had no problem. My exhaust is made of black gas pipe and would be simple and inexpensive to make. I wonder if stainless steel would be better.Good luck
Thanks for the responce. Was the tube the small one that supplies water further down the exhaust, after the water lift? Did you have to remove the manifold and if so, was it straight forward or did you need assistance? Was your boat a fresh water boat or salt?
Somebody and I believe it is Universal offers a freshwater cooling kit for the 5411. It includes a new manifold, water pump. It looks like a bolt in replacement.dgustafson@socal.rr.com
