I would like to install a small outboard motor. I have a 1999 8hp Johnson 2 stroke. I have an adjustable bracket that holds up to 25hp. My problem is that I don't know how to Bolt the bracket to the Transom. Do I need any special bolts? How high the bracket needs to be bolted? Does the transom have 1 thick wood from left to right or I will have to use a plate inside the transom? Is the 8hp good enough for this boat? I always go out offshore but I had some problem with my 90hp and just in case I would like to have an extra motor. Im a member of Towboat US but I dont want to call them every time I have problem with my 90hp. I will really appreciated any help<br />Thank you <br />--------------------------------------------------------------------------------<br />Posts: 96 | Registered: Mar 2003 | IP: Logged <br /> <br />moderator1 <br />Moderator <br />Member # 17886 <br /><br /> posted April 29, 2004 04:34 PM <br />--------------------------------------------------------------------------------<br />eula30,<br /><br />I am going to move this to the Boat Questions section. It really does not pertain to repair. Also, this may help someone else that is considering the installation of an auxilary bracket. <br />--------------------------------------------------------------------------------<br />Posts: 652 | Registered: Dec 2002 | IP: Logged <br /> <br />nautiJohn <br />Captain <br />Member # 29732 <br /><br /> posted April 29, 2004 04:55 PM <br />--------------------------------------------------------------------------------<br />This is not my field other than doing something similar, but here goes.<br /><br />The eight will push the boat at about 3 to 4 knots, which is enough to keep you out of trouble.<br /><br />As for mounting I suggest that you go to the manufacturers web site and see if you can obtain the mounting instructions. Or call them.<br /><br />As for the height of the motor, try to get the cavitation (anti-ventilation) plate even with or a bit below the bottom of the boat. Get the highest torque ( lowest pitch) prop available.<br /><br />As for the transom strength, I do not see enough weight or torque to require re-enforcement.<br /><br />All bolts need to be stainless, and depending on the accessability you may want to through bolt. <br /><br />mount the motor as close to the center of the boat as possible (next to your 90) so that the thrust of the 8 Hp is used to the maximum. <br />--------------------------------------------------------------------------------<br />Posts: 331 | From: Ohio | Registered: Jul 2003 | IP: Logged
.<br />You might put an aluminum plate or sealed plywood backing plate inside the boat for extra support. Use some heavy duty fender washers inside too. Your outboard powered boat probably has a solid strong transom all the way across (no need for backing plate-verify for yourself).<br />Seal the holes with lots of marine grade sealer.<br /><br />If you want to run with the kicker tilted down,the bracket should be high enough that the kicker skeg is a little bit above the transom when the bracket is in the up position. This way you dont have to tilt the kicker up to run main power on plane.
