Auxilary outboard bracket

[John Ellis]

I have recently purchased a new 195 DC here in Australia and would like to install an auxilary motor bracket on the port side aft. Before I begin drilling holes I wanted to check if there were any issues that I need to take into consideration. I understand that the Transom contains a high density foam material. Can anyone tell me if the various sections of roplene material that are screwed down ie. the section covering the fuel tank and the sections surrounding the aft circular hatches are glued down with a sealant as well as stainless steel screws. If not I would be inclined to removed the s/s screws and these sections in order to gain easier access to the cavities instead of trying to work through the small 6" circular hatch. The bracket in question is a TENOB stainless steel vertical mount manufactured in New Zealand and considered to be the best available, in the southern hemsphere at least. My plan is to drill 4 x 8mm holes through the transom only in such a position so I can access the interior in order to secure the nylock nuts. I have purchased 4 x 100mm x 8mm stainless steel bolts for the job. I also have some of the factory recommended sealant to use to maintain watertight integrity. Am I correct in assuming that the transom in cross section is basically a sandwich construction consisting of an outer and inner layer of roplene ?mm thick with the cavity between filled with high density foam.

Hi John. I checked with the factory for you on this and here is their response:

The parts are sealed as well as screwed down. The 2 main things to
consider are:
1. Sealing - which it sounds like you have covered. Make sure
you use RULE Elastomeric Marine Sealant, and

2. do not exceed your transom engine weight (256kg.) that includes the primary motor, kicker bracket
and kicker motor. The transom is a sandwich of Ropelene and high density 20lbs foam. The thickness of the Ropelene varies depending on where you are drilling but averages in the neighborhood of 1 to 1.5cm.
each side. Also to get better access to the inner transom wall you can remove the grayish white starboard piece that the 6" access plate in sitting in.

Thanks for the information regarding the installation. I'll post a photo once it's done.
