Topic: Boat Repowering
Question: What options do I have if I'm looking to repair or replace my existing Marine Engine?
Response: It doesn't take long when looking at the price of new boats to start investigating the alternative option of replacing or repairing your existing marine engine versus purchasing that new boat. This forum covers the options of marine engine longblocks versus bobtail marine engines.
When it comes time to investigate the options there are several things to consider; first and foremost is the age and condition of the engine being replaced. If the engine or longblock itself is bad, but the exhaust and other marine engine systems are in relatively good shape it can be a good economical option to simply replace the marine engine longblock. However, unless you intend to complete the work yourself one must always consider the labor associated with switching the attaching hardware over from the old marine engine to the new one. Common issues that arise when replacing a marine engine longblock are whether the intake manifold will match, making sure the flywheel is correct, making certain the ignition system matches properly, and making the necessary adjustments for mechanical versus electric fuel pumps. With marine engine longblocks there are either remanufactured or brand new options with the prices actually being very close to the same for either option. Have no fear, the PPT Guide to Repowering below will completely walk you through the process.
