Boat and engine suitability
- Suitable for vertical or appropriately prepared transoms on sailing yachts, motorboats, fishing boats and inland-waterway craft.
- The 20HP figure is a maximum power limit; the engine must also weigh no more than 40kg.
- Four-stroke outboards are often heavier than two-strokes of the same horsepower. Always use the actual engine weight.
- Confirm shaft length, propeller immersion, steering clearance and full engine tilt before drilling the transom.
- Not intended to compensate for a weak, damaged or unsuitable transom.
Installation and safety
- Installation should be carried out by a competent marine engineer or boatbuilder.
- Use marine-grade through-bolts, large washers or backing plates appropriate for the transom construction.
- Seal all drilled holes to prevent water ingress into the transom core.
- Check that the bracket locks positively in every working position and that the engine cannot contact the hull.
- Inspect springs, pivots, pad, fasteners and transom structure regularly.
Frequently asked questions
Can I fit a 20HP four-stroke engine?
Only if its actual dry and operating weight remains within the 40kg limit and the boat transom is suitable.
Is the mounting pad made from wood?
No. It uses polypropylene, which does not absorb water or rot like an untreated wooden pad.
Will it fit every boat transom?
No. Transom angle, thickness, strength, available space and required propeller depth must be checked before installation.
Are transom bolts included?
Fixings are not stated as included. Select marine-grade hardware suitable for the boat's transom construction.
