Last week saw us heading to Pembroke Dock, West Wales, with a fully rebuilt Volvo Penta KAD43 6-cylinder engine loaded into our new Kia PV5 van.

We approached the journey with a little trepidation as it was the van’s first proper long-distance trip, and first away from home charge, but it performed brilliantly. With just a quick charging stop at Chippenham on the way there (and another on the return journey), it proved to be more than capable of covering the distance.

Our task was to refit the freshly rebuilt engine alongside the second engine we had previously rebuilt, before reinstalling both sterndrive units. Once everything was back in place, connected up and ready for the next stage, we loaded one of the original engines into the van and headed back home.

That engine is now back in our workshop, where it will undergo a complete strip-down, detailed inspection and a full rebuild.

Another successful trip completed and another step towards getting the boat back on the water. It’s always rewarding to see our workshop efforts coming together on site.

It’s not all glam… Crawling right down into a small locker at the very back of a yacht to get access to and remove a non functioning webasto Airtop heater for a strip and overhaul. Laying underneath the bathing platform with my legs laying up the side of the hull was not the most comfortable spot but allowed me to easily get to the fixings. Looks a lot more room than there actually was down there!

Very pleased with my new van! Kia PV5 Cargo long range, SB Marine are joining the electric revolution!

Another job completed on a local yacht that hit a channel marker buoy causing significant structural damage. The impact had broken the bow support bulkhead so it needed removing, internal hull repairs, a new, beefier bulkhead making up out of thicker plywood and all bonded in using West system epoxy. The internals were all then coated with gelcoat in white to match the original and all the individual strip panelling refitting. Externally the hull had to have some cracking ground out and relamination before several coats of gelcoat to finish off the repair.

Neal’s been a busy chap recently with some heavy grp damage repairs to a Border Force vessel. Digging into all the laminate damage on the bow, repairing with west system epoxy and fairing with a matching blue gelcoat, as per the original colour, then applying a grey wrap to match. Also a new stainless steel keel band strip and all finished off with a new section of rubber fendering.

Meanwhile Simon repaired the sterndrives, that had a leaking seal and also a bent propeller shaft from an underwater impact.

Another great job completed by the team at Gillingham and the boat ready to go back to service.

Weekend work has been continuing to sort out our portacabin. The old tired interior has now been stripped out so we can insulate and transform this into our new office and parts store. With the new workshop now in use, we can accommodate all your boat repairs at Gillingham Marina.

This week in Gillingham, we have been assisting with fitting a new higher capacity water pump onto the deck of the water injection dredger, ‘Melwey’. The pump has the mounting studs welded to the decks, and then the intake and outlet pipes, hoses and connections needed upgrading to match the increased pipe sizes and water capacity. Work was finally completed and tested on Friday and she can now go off to work. The increase in water flow from the original pump system was very impressive!

Big news! 🎉

We’re excited to announce that in order to improve our support for boat owners in the marina, we’ve taken on a workshop at Gillingham Marina! We’re currently moving in and getting everything set up. Our portacabin, which previously served as our workshop, will be transformed into our new office and stores and will be located right in the boatyard — making us far more visible and easier to find.

Best of all, we can now bring boats fully undercover and into the workshop, allowing us to work in all conditions. This means more consistent turnaround times and far less disruption from the weather. The new space will be a huge advantage for GRP
repairs and antifouling work, and we can’t wait to put it to good use!

Visit us in store or contact us for parts or to book in your servicing for Nanni, Vetus, Thornycroft and Volvo Penta engines.

Getting ready for the season? Take advantage of our great deals on Nanni and Vetus engine packages.

We also supply all your electrical and electronic needs, with leading brands such as Raymarine, Garmin and Victron Energy. If you’re considering a chart plotter or radar upgrade this season, give us a call — we’re here to help.

Thank you and we look forward to another great season supporting you all!
