Gustavson 2725E spares are no longer directly available. For the Headertank/heatexchanger we reconmend the Bowman FH220 as a replacement. For Oil cooling we can supply an integrated cooler similar to original, however this is an expensive solution. A alternative and more cost effective solution is to remote mount the Oil cooler. Finally if you don't use the engine above 1750RPM, discard the oil cooler to prevent condensation build up build-up of corrosive acid.

We often get told by owners that they find headertank water levels low when they do routine checks and despite then filling up, they again find the level low again the next day. ​To keep the headertank coolant at a good working level try fitting a coolant expansion tank.

If you notice your engine emitting blue smoke from the exhaust it could just be a sign your overfilling the sump for your particular engine configuration. Keeping oil topped up to the dipstick maximum may be causing excessive oil splash which then results in higher oil consumption and worrying exhaust blue smoke.

"De-smoking kit" includes extensive work on the injection pump and the supply of solenoid valve and associate fuel pipes. It works by starting the engine on only 3 cylinders that have to work extra-hard to drag the other 3 cylinders along, thus warming up the three firing cylinders to get rid of the white smoke in just a few seconds.

With dunked engines the main thing is prompt action. Every day you delay makes things more difficult. We saved a pair of 8.3 litre Cummins engines that went under a few years ago and though it took a couple of days to recover the boat and start drying out, within another day we had them running again, since when they have given little consequential trouble.

Latch release cylinder for 80-91 series sterndrives has not been available for many years To release the latch in order to allow the power lift to work, we suggest drilling a little hole in one of the forks of the latch, attaching a thin cord to it and running it to a convenient point above waterline where you can pull it to release the latch. When removing the failed cylinder and hose, the distribution block will need to be plugged with a 3/8" UNF plug.
