Repairs & Maintenance

Your One Stop Shop
At Marco Boats, we don’t just build boats …


Taking care of your boat is a high priority for the team at Marco Boats. We carry out marine insurance from the more common broken windscreens right through to damaged hulls from on-water impacts and tailoring mishaps. Marco Boats frequently repairs alloy boats with corrosion problems and are happy to work with you, if you wish to keep costs down, by preparing the boat for welding, or you can have us take care of the whole repair.

You can even have the trailer under your boat replaced or repaired. Rusty parts or ill-fitting rollers can all be taken care of for you. We also do repairs to alloy truck trailers, truck headboards, bull bars, etc.  For maintenance advice click here.

See the pictures below for examples of our boat repair projects.

Fibreglass is fairly maintenance free. But it does need to be cut and polished probably once a year to keep the gel coat in good condition. Once cut and polished it has to be waxed as well or the finish will deteriorate faster than if nothing had been done at all.
Stainless steel rails should be properly polished once a year, mostly around where the rail meets the fibreglass as this is where pit marks or possibly rust marks will occur depending on the age of the boat. Once pitting has taken place it is hard to fix and can lead to bigger problems.
When storing the boat it needs to sit noticeably bow high with the bungs open. This will allow air to circulate through the hull and will allow any moisture in the boat to evaporate on warm days. The most common cause of serious damage to fibreglass boats is stringers rotting out from inside where water has been sitting and this is very expensive to repair.
Any fuel spills should be cleaned with soapy water but don’t let the fuel sit for too long as most fibreglass trailer boats are made from a resin that will go soft if faced with prolonged exposure to fuel. Again, this will be an expensive repair.
If the boat is being stored outside for prolonged periods then a proper cover should be used. The cover should not be able to contact the fibreglass where the cover is likely to stay wet for long as this can cause osmosis in the fibreglass. The same goes for wet rags, clothes, lifejackets mats on the floor and anything else.
Also, the cover should not part cover sections of the boat, e.g. the bow or the transom as this will cause the gel coat to fade in the exposed part but maintain its colour under the cover. This again will be very hard to rectify if it can be at all.


The biggest problem is salt build up. A good hose down and wash is fine for normal everyday use but more is needed on occasion. On bare alloy a spray and wipe of Inox, or similar moisture repellent, once every three months or so will keep the alloy in good condition and help to reduce water marks.
Once a year it is a good idea to run fresh water through the bungs into the sealed chambers. Done with salt away is the best, potentially even some dishwashing liquid, but nothing too corrosive. Once say 20-30 L is in each tank put the bungs back in then tow the boat for a while to get the water in and around all the areas. Then empty and rinse out.
For painted boats a wax and polish once a year is needed to keep the paint in good condition, but it is a good idea to keep an eye out for bubbling in the paint. Bubbling is unavoidable with aluminium and will always happen at some stage. It is easiest to have the small bubbles touched up once a year to stop them getting too bad and the bigger they get the faster they spread.

Fitting after-market parts

SS to a minimum, don’t drill through sealed chambers, any electrics should be grounded back to battery. Any carpet or mattings need to be properly dry or removed to be stored for long periods as this speeds up the corrosion process.

Wooden floors in alloy boats should be lifted up at least once every second year; flotation removed and cleaned of salt; the floor washed of any build-up of leaves, salt, etc; bottom of floors checked for rot; everything allowed to dry completely then put down again

Trailer maintenance

Grease coupling to avoid wear. Pump the handbrake on braked trailers a couple of times a month. This keeps everything moving and reduces the likelihood of brakes sticking. Check the trailer plug. Opening the slits in the connector a little bit gives better contact and will frequently fix tail lights that aren’t working.
