Honda OB throttle adjustment
My propulsion is a 1979 Honda BF75 7.5 HP longshaft outboard. Has run extremely well for the past 6 years we have had our boat. I have serviced this at Honda dealership and seems to have years left in it.

This past weekend went for our first sail. Winds were gusting 15knots in the marina and 23 on the water. Engine started on 2nd pull and ran well. However it was idling very high. When I twisted the grip to lower the idle speed it did lower but was still quite high. Almost too high for shifting gears and definitely not great for manoeuvering in a marina. Ran well on high speed though when motoring outside of marina.

Anyone have a thought to where the low speed adjustment is on this motor? It is basically the same as the 10 HP of the same era. May also just be a case of lubricating something ... don't know.

Was a fun sail anyway and an interesting docking.

Most motors have a fast idle adjustment that causes the engine to idle faster when it is just warming up. The problem sounds more like this may be sticking, rather than the idle speed being set wrong, if it has been set properly previously. Usually, a little carb cleaner will clean the fast idle adjuster so it doesn't stick.

Was back at the boat on Wednesday. The throttle cable and the lever it pulls were not resetting fully. A very liberal dosing with Fluid Film lubricant on the cable and this assembly resolved the problem. Wish they were all this easy.
