30 YRS WITH OMC ,YOU CAN PROBABLY ANS. MY QUESTION,,DOES MY 1967 20 HP JOHNSON HAVE A TILT LOCK ?? WONT STAY TILTED AT ANCHOR,,SO AS TO KEEP PROP OFF ROCKS WHEN AT ANCHOR IN SHALLOW WATER
Tilt lock feature isn't for that purpose; it's for trailering. Tighten the tilt tube end nuts to increase friction in the tilt to keep the motor from dropping when tilted.
