Can anyone give me the proper placement for my Outrage? I will be repowering soon and I would like to get it right the first time.

The transom has been repaired and there are NO holes in in at the moment. It would be nice to drill them out exactly where they should be. And.... not rely upon the dealer to determine the correct height.

Thanks for your help.

It would be beneficial to mention the size of the boat, and also to not require the reader to refer to the TOPIC line to comprehend your article or question.

Regarding where to drill the motor mounting holes in the transom, I would recommend following the template that comes with your motor. Most motors now conform to an ABYC standard hole configuration. I would assume most other devices intended for transom mounting of engines, like a set back bracket or lift plate, would also conform to that standard.

The general practice in recreational boats is to drill the holes in the transom in a standard and well known location, and to make the adjustments to engine height by selecting different sets of holes on the engine's mounting plate. That is why there are four sets of holes on the engine and only one set of holes in most boat transoms.

In some cases, due to particular boat transoms and in combination with particular engine mounting brackets, some boats have been rigged with holes drilled in an non-standard layout. This happens in older Boston Whaler boats where the depth of the transom splash well is insufficient to accommodate the lower mounting hole of the now-standard engine mounting hole layout.

If your particular boat has this problem you will have to accommodate that in some way. In the past this has been done in a variety of ways:

--use lag boats for lower mounting and do not drill through holes;
--use through holes but drill lower holes in non-standard fashion, usually higher than the standard hole would be, and use a "blind" hole in the motor mount to accommodate the bolt;
--open up the engine splash well and drill hole in standard location, then bury bolt in hull and re-glass the well.

This last arrangement has been done, but I don't recommend it. I have also seen installations where the lower hole was drilled on an angle and the lower mounting bolt installed at a slight angle. Again, probably not the best solution.

I am not intimately familiar with all the transom and splash well dimensions on all sizes of 1971 Boston Whaler OUTRAGE models, so perhaps you can clarify what the problem is, assuming that you cannot use the ABYC standard engine mounting layout.

I would not recommend drilling holes in a non-standard layout to accommodate special requirements of a bracket or jack plate. Instead I would drill standard holes in the bracket or jack plate to match the ABYC layout. If that were not possible I would get another style of bracket or jackplate.

As for your question, "Can anyone give me the proper placement for my Outrage?" I would recommend placing your Outrage in temperate fresh water and enjoying use of it as much as possible during the boating season.
