However, there may be times when a boater strays away from these recommendations. If you decide to make adjustments, please consult a marine engine dealer about the boat design. This is somewhat similar to #2, in that you are again measuring with a If you said you have a pontoon or a larger style boat such as a bass boat or speed boat, I would be pretty confident in saying it needs a long shaft. Outboard shaft length plays a crucial role in the performance of your boat. Determining Your Boat Transom Angle The transom angle - commonly measured in degrees - is the transom's vertical inclination. How to Raise Outboard Motor on Transom? - Raising the Outboard Motor However, the motor should not be raised more than 5 inches above the standard position. So if you are measuring the outboard shaft length for the powerboat, planing boat, or any boat for which the speed is the priority, take the outboard shaft length 1 to 1.5 (depending on your boat types) shorter than standard would be better. Copyright 1999-2023 Boats Group. So if you are measuring the outboard shaft length for smaller boats, inflatables, dinghies, sailboat or other low-speed work boats, the cavitation plate is often about 2 below the bottom. Adjusting the mounting height of an outboard on the boat transom can affect performance and every boat can be different, so actual on-water testing is best. Step 3: Add another 10 cm (4'') to the previous calculation for the final ideal shaft length. document.getElementById('cloakd53b59933f6c3f2e8b59f1b4a6d41fa5').innerHTML = ''; There is a simple test to see if your outboard motor is set at the best height. As with anything, there are exceptions to the rule. Ten years ago I bought my first boat. s.setAttribute("rel", "stylesheet"); The average transom angle is around 14 degrees. Your goal is to measure how the outboard will sit, so start from the clamping plate and follow the centerline of the hull. 1 0 obj Buying a boat can be an exciting purchase. Actually there is no designated letter for short shaft. The transom is the flat vertical section at the rear of the boat. A1: Broadly speaking, the outboard motor shaft length for pontoon boat, bass boat, or other larger boats should be long shaft. If your boats transom height is 15-16, a short shaft engine is required, and if it is 20-21, a long shaft engine is required. This, however, is not recommended for the beginning boater. August 9/08). function gtag(){dataLayer.push(arguments);} It is possible that the motor could hang low while transporting on the boat trailer causing future boat repairs. Other factors to consider when determining the mounting height of an outboard are related to performance. Boaters who consider going with a higher mount can see increased speeds. The clamp bracket on the latest Mercury Four-Stoke-model outboards has five mounting bolt holes spaced .75 inches apart. Having the cavitation plate a bit lower than the transom is preferable to having it too high. You dont have to be a mathematician to determine the correct boat transomangle.
