Title: Outboard Motor Bracket Modification 
Author: Terry F. Ellis and Ron Stephenson 


The blue hull First 21.0 has double rudders. This allows placement of the outboard bracket on the boat's center line, between the two rudders. This is ideal for weight distribution. However, the factory OB Bracket was a "sliding" type vs. a "spring" loaded type. This required lifting the combined weight of the motor and aluminum bracket to raise or lower the motor. It is hard on one's back and could pinch fingers too. So, my friend replaced the factory bracket on his First 21.0 (Hull # 34) with a spring loaded OMC type. To mount it, a boat repair shop adapted the exsiting stainless steel bracket (90 degree angled 1/4" thick piece) on the cockpit sole. This has worked very well with his 4 HP Yamaha outboard engine. It is also more attractive than the original factory bracket.

For this modification, you must remove the wooden panels inside the cabin on the starboard aft side quarter berth to gain access to the inside of the transom. The space available to reach the nuts on the thru transom bolts is barely sufficient.

The factory placement of the outboard bracket on my First 21.0 Classic (Hull #58) was a heavy and sturdy spring lifting design by OMC. It was securly bolted on the starboard side of the boat's transom. It was designed to accept up to an 8 HP outboard engine with a long shaft. I had a 4 HP Johnson with standard (15") shaft. I did not want a 65 pound, 8 HP engine, I felt was too heavy and powerful. With the factory bracket swung down to its lowest position, my 4 HP Johnson would not reach the water. I removed the factory bracket and patched the 4 bolt holes with silicon sealant and "Marine Tex" epoxy. I replaced the factory OB bracket with a lighter weight OMC spring loaded bracket (for engines up to 6 HP). I relocated this bracket lower on the transom, as near to the center line of the boat as possible without interfering with the rudder. I drilled three new holes in the transom and fastened this bracket's support piece with 3/8" Stainless Steel bolts (1 upper right and two lower bolts). The lower holes ware well above the hull waterline. To fasten the upper left corner of the bracket support, I made a "knee" out of 2" thick mahogany. I bolted that knee to the cockpit sole and then secured the fourth bolt of the OB support bracket to it (like a shelf support knee). I stained and varnished this "knee" to match the other mahogany trim on my boat. This has worked perfectly for me for three years now. The new location brings the weight of the OB closer to the center line and allows the motor to run deep enough to avoid cavitation in high waves. Also, I can now pull the starter cord from beneath the transom support beam, through the boat's open stern section.
