Hi all
I am new to Hemi inboard motors and am working on a 4.5 m Hullcraft inboard ski boat fitted with a 265 Hemi. The home made extractor type water cooled exhaust manifold is shot and I would like to buy a cast alloy or stainless steel type, can anyone point me in the right diection?
many thanks

If I recall the 265 Hemi was only used in Australia so you will need to find a Australian company to help. I do have a guy I know down there http://www.hitekmarine.com.au/ Tell them I sent you .. they are a great bunch of folks!

Spoke to Noel. The solution was to remanufacture from S/S, the extractor style system currently in use. Finsbury raw water pump presently in use. The Ski boat is only used in a fresh water environment. Cost to manufacture app $500.00 AUS, Rolco alum manifolds app $1500.00. Could also entail the installation of a heat exchanger depending on the capacity flow of the raw water pump to supply water into the manifold. My system is a combination of Alum manifold and heat exchanger. Salt water usage. Jamie, how does your system operate? I wonder if the T Stat is removed! Frederick Pel |

Thanks to Frederick, Jamie and others, think I am on the right track. Cheapest options is to go with modified auto extractors, system is very simple with a Fynspray pump circulating water directly through engine and manifolds, no tanks, risers etc. As boat is worth about $3000, need to watch the outlay
thanks to posters

Noel for my interest, have you removed the T Stat? When you have the new extractors manufactured would appreciate some photos. After she come back from out west if you would come back with some operating temperature range. Frederick Pel |
