40HP Outboard Install -DIY Job or Not?

[VA_Fishnut]

I've slowly been rerigging my motorless boat preparing to have a motor put on. Everything is installed but the engine controls and the motor and the holes are leftover from the previous motor. Just how hard is it to install a 40HP remote outboard and hook up the controls? I've suprisingly been able to do alot of the rigging myself so far and would hate to pay extra to have someone do something I can do myself. Anyone installed their own motor in the 30-50HP size range? Would like to hear your thoughts and suggestions. <br /><br />Also, I have seen some discussion whether installing the motor myself may void the warranty or it has to be inspected by a certified technician in order for the warranty to be activated. Does anyone have first-hand knowledge of this?<br /><br />Thanks, <br />Brian

You should be able to do it; I installed an older 100hp Merc on my boat. Verify that the existing holes are of the same pattern as the new motor. If they are... good, if not, you will need to fill the holes and drill new ones. Make sure all bolts through the transom are sealed with 3M 4200, 5200, or equivalent. I made small backing plates for the bolt/nut to help spread the load on the backside of the transom. If you are drilling new holes, you need to ensure that the motor will be centered, and also at the right height (height also applies if you do use the existing holes).<br />Run the harness and the steering cable under the gunnel, and mount the control box in the desired location.<br />For me the most difficult parts were hooking up the steering cable (very little clearance -had to hook it up before actually bolting down the motor), and physically lifting the motor (it took 3 of us to lift it into position).<br />On mine, I installed a metal plate to the outside of the transom, to help cover the old holes, and to dress things up a bit. I filled the old holes with 3M 5200; I'm sure others have used Marine Tex or other products.

I'd let the selling dealer do it. There are certain things that have to be done by the selling dealer or you can endanger the warranty. Most reputable dealers will not sell an outboard out of the box. Their contracts with the manufacturer requuire that they set up the motor properly. The disreputable ones are more likely to engage in such practices and you really don't want to deal with them. If they're willing to screw the manufacturers, they're just as willing to screw you.
