Testimonials

a year ago
Althorne marine recently installed a Beta engine in my boat and I found them to be approachable, conscientious and considerate. The price was very reasonable and the installation was executed to a high standard, as has been the case with all the work John and Steve have carried out for me over the years.

Steve serviced my engine a Mercury and checked everything, winterised it, perfect job and reasonable price and no mess would recommend and use again.
