Make sure there are no obstructions for the nuts and bolts on the transom on the inside part of the boat. If there is, take measurements and transfer them to the other side to have a clear picture of any obstructions.
Place the wheel where is best functional and make sure that when you rotate the motor left and right that the wheel doesn’t get in the way.
Hold the wheel in place against the back of the transom: with a pen mark the top hole closest to the end of the boat on the mounting bracket. Use your measuring tape to make another mark on the same place alongside of the transom. Use your straight edge to pull a accurate line between the two marks, this line should be perfectly parallel to the top of the transom. Dill two 6.5mm holes on the marks.
Using one nut and bolt fasten each wheel to the transom. Set the wheel so that it is parallel to the transom; make another mark in the centre of the hole alongside the hole that is fastened. This mark should be directly on the line that you made earlier on, drill another hole on mark.
Fasten the second hole that you drilled and drill the other two bottom holes.
Remove the wheel system entirely and place a good amount of marine silicone on the bottom of the base and around the holes. For extra caution and peace of mind, place a bit of silicone inside the drilled holes.
Refit the wheels tightly using M6 Nyloc nuts, bolts and washers. Make sure you ask for Marine grade stainless steel when buying your fasteners. Each nut, bolt and washer should have a stamp with numbers 316, these numbers indicate the grade of the stainless.
Clean up the access silicone using warm soapy water or mentholated spirits.
