How To Repair Broken Outboard Fin
The skeg of an outboard or sterndrive gear case provides much directional stability and steering ease. Whether caused by running aground or due to some land-bound calamity, a cleaved or damaged skeg adversely affects treatment. In some cases, a welder can repair your skeg. When I needed to repair the bent skeg of the Yamaha outboard that powers my Edgewater 228 CC charter boat, I elected to do it myself using a Megaware SkegGuard. Made of mirror-polished stainless steel, a SkegGuard works equally long equally at least iii inches of stub remain of the broken skeg. Hither's how I did it.
Skill Level: 1/5
Cease Fourth dimension: 2 Hours
Tools and Supplies
* Megaware SkegGuard ($99.95, various sizes)
* Jigsaw with bi-metal bract
* 3M Scotch-Brite pads (light-green or red)
* Drill motor
* Cobalt or HSS drill bit (1/4-inch)
* Mallet
* Manufacturing plant-bastard file
* Wire brush
Removing the gear example also gives you a take a chance to supercede the water-pump impeller, housing and gasket to ensure max cooling performance. Information technology's relatively easy on about outboards. Check your owner's manual and do-it-yourself videos on the Web for your make of motor. Exist sure to keep the bolts and washers that connect the lower unit to the midrange section of your outboard engine in a safe place (like a large cup) so they don't go lost prior to reassembly.
Cutting Flush
I used a jigsaw fitted with a bi-metallic blade to cut the aptitude skeg off and present a clean and level surface. A SkegGuard requires at to the lowest degree 3 inches of stub remaining from the original skeg in social club to be affixed. Don't cut off also much.
Prep the Surface
Use a manufacturing plant-bastard file and/or an abrasive Scotch-Brite pad to deburr the cut edges of the outboard or sterndrive'south skeg stub. Use a strong-wire brush to make clean off metal bits and filings. Wipe clean with a solvent-dampened rag.
Dry Fit
Using a plastic or wooden mallet, or borer with a hammer and a scrap of wood, tap the SkegGuard into place over the old skeg and cheque everything for a proper fit. Tap it firm enough to make certain it is well-seated on the stub of the original skeg.
Drill Holes
Using the SkegGuard with its pre-drilled holes as a template, drill two 1/four-inch holes completely through the skeg. Exist sure to drill straight and foursquare. A high-speed steel (HSS) bit will piece of work, but I used a Cobalt bit, which dissipates heat better.
Insert Bolts
The SkegGuard comes supplied with bolts in various lengths to adjust varying thicknesses of skegs. Locking sealer is pre-practical to keep the bolts from loosening. Insert the advisable bolt and use the supplied hex tool to tighten.
