Re-Power Without Blowing the Bank

Re-Power Without Blowing the Bank

This is a short overview of some of the options you have when it is time to re-power or find an engine for a restoration project. One of the things we like at Wave to Wave is getting the best bang for your buck. We are all about restorations, upgrades and improvements for everyday boaters. There are plenty of magazines catered to guys who want to spend $100k re-powering but the reality is most of us want to get on the water and we don’t have money to burn. But, whether you are on a tight budget or can spend rap video money, you want to get value for your dollar and reliability from your engine. Here we look at value oriented re-power options for a range of boaters looking for OE replacement type power-plants. Nothing exotic but in the 300 HP to 450 HP horsepower range. 

Speaking of value, one thing you see often in forums and online is using automotive crate engines or going to car “shops” for custom builds. This is fine and well if you know what you are doing. There are key things you want to look for and may have to alter from the camshaft, gaskets, oil pan, ignition, brass plugs, flame arrestor, oil cooler and exhaust manifolds etc. That is easy but the caveat is performance, re-sale and warranty. The marine specific engines often save you time and money in the end, especially if you factor in warranty and resale. An engine built by Joe’s Garage, might be great but the guy buying your boat next year has no clue what internals were used or the specs. Many have had success with the GM crate engines, no doubt, but keep in mind, you lose the warranty and when you factor in the marine parts; you are really close to a MerCruiser remanufactured engine or a turnkey from a marine engine builder. 

Here are a few options and horsepower ranges for re-powering your boat or project. I know there are many more but these standout for everyday performance boaters. 

Mercury Remanufactured

Mercuiser 357 4V

Mercury

From the 320 HP 357 MAG 4V and 383 stroker to the 540 Mag, it is hard to beat remanufactured engines from Mercury.

The value is hard to ignore, Mercury remanufactured means you pay a small premium but you get a stout turn key package, MerCruiser warranty and your resale will be better than everything other than a brand new MerCruiser. Plus, you get the option of the 383 350 HP, which is 370 HP with headers. Prices can change but small blocks are in the $6k range to $9k complete. Big blocks come as the 496 HO 425 HP and 540 HO 450 HP.
