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.

This page also ties in with my work on Lithium systems as it’s normally necessary improve an alternator charging system when installing a Lithium Battery sytem – visit my Lithium page.

Installing a washing machine is a big deal and can turn a holiday boat into a liveaboard. It’s often necessary to improve alternator 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 particularly poor. 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 latest 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 domestic 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 the 175 amp alternator as fitted to the later Beta 43 & 50.
