We have received help requests recently for Gustavson 2725E engines.These engines were often fitted into Trawler yachts built in Taiwan.
Nils Gustavson AB of Stockholm, Sweden, (Toby Gustavson) marinized these Ford of Britain built engines, however this business ceased trading many years ago during the 1980's.
Gustafsen supplied a many engines used for trawler yachts built in Taiwan in particular the Gustafsen 2725E.
We are finding the combined Headertank Heat-Exchanger are now at end of life and require replacement on otherwise serviciable engines. The Bowman
FH220 is a good replacement as fits directly and needs just one hose for the jacket water connection to
the circulation pump.
The original Oil cooler was combined with the Headertank. This requires a different tubestack and end caps. In addition a spacer, oil cooler body, tubestack and a special tie-rod and nut are required. This solution is an expensive route, although will replicate the original instalation.
A more cost effective way is to use standard components as used on other Ford 2725E maranisations. If the oil cooler section is good, use it with a shortened centre
rod and the cap from the other end of the tank, and then find somewhere
convenient to mount it.
If the oil cooler has failed then replace with a Bowman EC80.
If the engine speed does not exceed 1750RPM then discard the oil cooler
and use one of the hoses to bridge between the two ports on the oil filter
mount. Using modern 15W/40 mineral oil, without a cooler, the oil temperature will be optimal at a temperature just exceeding 100 deg.C. This ensures any
condensation from the oil is evaporated and helps prevent the build-up of corrosive acid.
