New Life for Old Engines... Replace, Repair or Rebuild?
Consider all options carefully or risk spending more money than the boat is worth
By Mike Milne
Regular engine maintenance and occasional repairs are part of power boating. But when an inconvenience turns into a catastrophe and their boat’s engine fails, boaters face the decision of whether to replace or rebuild.
Depending on the age, value and condition of the boat, the need to repower or rebuild one or two engines could spell the end of a boat’s useful lifespan. Engine failure doesn’t have to be a “death sentence.” However, boaters need to consider all options carefully or risk spending more money than the boat is worth.
The dilemma is further exacerbated by the difficulty of rebuilding an engine properly (see Your Rebuild sidebar on Page 53), as well as the shortage of technicians and in-season shop time in many marinas. Pulling an engine, determining cause for failure and repairing that fault can be difficult and costly, especially if more problems surface along the way (technicians call it “parts creep”) or the fault is improperly addressed or misdiagnosed. Once the cost of removing and/or disassembling an engine and replacing individual failed parts is tallied, a new engine, complete custom rebuild or a factory-remanufactured replacement engine becomes a financially feasible option.
