I specialise in alternator and charging systems upgrades – It’s possible to significantly increase and improve the charging performance on many engines.

I’m still developing this page and have described some specific upgrades (Isuzu, Barrus, Vetus) if you scroll through my blog. I’ve done certain upgrades multiple times on some specific engine models – Isuzu, Beta, Barrus, Lister, Vetus etc… and will add them to this page at some point.

Installing a washing machine is a big deal and can turn a holiday boat into a liveaboard. It’s often necessary to improve charging performance in order to keep up with a large inverter running a washing machine. I can complete the job from scratch  – charging system, battery monitor, inverter and washing machine.

It’s sometimes possible to fit a smaller 1300 watt heater element to a washing machine to decrease loads on the inverter/charging system – please call for details.

Isuzu 175 Amp Alternator Upgrade.

The Isuzu engines are excellent but factory domestic charging setup is terrible. I have a 175A upgrade which is available for most of the 4 cylinder engines. It requires a 6PK crank pulley which is available if your engine doesn’t have one fitted.


Barrus Shire Engines

I have an upgrade on the ‘single belted’ Barrus Shire replacing the low output 80 amp alternator with a much more powerful 90 amp alternator – fitted to over 100 boats over the last 10 years. Other upgrades available on the Barrus Shire engines – some details if you scroll through here.


Beta Marine Engines

It’s possible to replace the troublesome solid aluminium poly-V pulleys fitted to the travel power and alternators on some Beta 38, BV1903, Beta 43 & Beta 50 engines. A smaller freewheeling pulley is available for the 95 Amp Iskra alternator or this can be replaced with a 175 amp alternator as the later Beta 43’s and 50’s have.
