Designed to protect and perform, the Blackfin Replacement Skeg is made from durable high-impact nylon composite featuring two tapered wings on each side for structural reinforcement and lift at every angle of engine trim. The Blackfin also features a sacrificial node on the bottom which limits the engine's skeg from plowing into underwater objects, and is shaped to turn the engine slightly on side impacts for more prop protection.
To determine the Blackfin model for your engine, measure from the front of the prop to the tip of the gear housing. Simply match this measurement to one of the Blackfin sizes listed below.Note:
The MerCruiser Alpha One when measured falls into the medium category, however it will require a small Blackfin.

My second Blackfin Skeg. First one to repair broken fin on used 17.5' Bayliner purchased last year. Skeg 1 ran all season with no issues, really improved driving/turning boat. This season didn't raise motor when trailering, bam, knocked skeg off - shot somewhere into lake, purchased skeg 2 without hesitation. Great inexpensive fix - compared to lower unit, easy to install, but not made to drag bottom or rocks or even a concrete boat ramp.

This was a $100 mistake. The composite skeg did not fit tight against the skeg on the motor. I had to put additional adhesive to try to hold it on. Needs to have way to bolt or screw on. It last three trips and fell off.

I have fished the Rum River in Minnesota for 50 years, has some very rocky places. At some point I think Ive hit everyone of them. I used the Blackfind to repair/replace my old skag on a 25 hp 4stroke Evenruide. Had some doubts about it but was surprised how strong it was. Working our way up river in about a foot of water the skag made contact with the rocky bottom as it did the boat lifted up slightly (I was waiting for the crashing sound the prop usually makes) we idled along perhaps 25 more ft. No prop contact.Slipped into a little deeper water boat settled back to normal.Checked prop at landing looked like new! Would recommend trying if your thinking about a repair/protection for your motor.
