If you're thinking of re-powering or replacing and old engine, installing a bow thruster or even optimising your running gear or transmission - at Mariner we can advise you on the right way to go, based on your needs and budget.
Consider the conditions in which marine engines operate - hot, damp, cramped with salty bilges, intermittent use and irregular maintenance. What they really need - cool and dry air - is rarely what they get.
Repairs will keep you going, but eventually weak links appear in the chain. When it comes to rebuilding, parts can be expensive and hard to find, plus you need a skilled mechanic to do the job.
Rarely are the older, raw-water cooled engines suitable for rebuilding as the internal water passages in the block and head are corroded beyond salvation.
Ultimately, a rebuild can cost money that’s better invested on new technology. As a rule of thumb, don’t spend more than 40 per cent of the full cost of a replacement.
You can sell or trade your old engine if it hasn’t totally given up the ghost, but it needs to also be kept in mind that the outlay on a new installation will rarely be offset by a rise in resale value. You do it because you want to enjoy trouble-free use of your boat and to limit future expense.
