mounting methods

[jvb]

i am new to this, so i apologize if its a dumb question. i am replacing a motor in a 81 glastron. the existing motor is mounted with bolts through the transom. the motor i plan to switch it to looks like it is mounted with the little screw clamps. it would seem to me that the bolt on method would be more secure and less 'bouncy' than the clamp on. it would seem that the bolt on would result in less stress to the transom.<br /><br />can all motors be mounted either way?

Re: mounting methods

What engine are you replacing, and with what engine, JVB?

Re: mounting methods

jvb, All motors of more than 25HP should be bolted to the transom with throughbolts. The clamps make it convenient to mount the OB, but will allow it to fall off if you hit something.<br /><br />If you look at the bottom of the Merc's transom clamps, you will see holes for the installation of bolts.

Re: mounting methods

ok, cool - so it should work either way? i definitly want to bolt it on...

Re: mounting methods

jvb, Just so you know, I had my '59 Johnson Fat-Fifty clamped to the transom of my runabout (no bolts). As I cruised at a blistering 11 MPH, I just nicked the bottom, and that 200# plus motor popped off the boat, broke the steering and control cables and sheared the electrical line, and fell into the drink.<br /><br />It took me three days to find it in only 4.5 feet of water. It however, lived to run another day, proving that 60 hours of salt water could not defeat 30 years of grease and oil.<br />Don't try this with any "modern" motors.
