I'm with Russell on this and have had a valve on my Albin since '07. The ZF valve instructions say to never exceed 1200 RPM's when engaged. I prefer to not exceed 1000 RPM's as precaution. If installed it's imperative to photo tach your engine and tune your RPM gauge.Russell wrote:I have a trolling valve and would not have anything else. ... the trolling valve requires nothing and might add to the value of your boat. If you keep the engine at idle speed a trolling valve does not harm the transmission. There are thousands of these things in use by recreational fishermen and charter captains and if they caused harm it would be well known. Your speed needs to be adjusted as you turn into and out of the wind or current and you do it by pushing the trolling valve control in and out.
One trick I learned from charter captains is to keep a sock or cloth tube tied to the throttle and stick that on the handle when the trolling valve is engaged. Accelerating to higher RPMs with the trolling valve engaged will ruin the transmission. It might not be you that does it but one of your fishing companions that takes over not realizing the valve is engaged.
As a reminder that the valve is being used I run a short length of line tied to a cap that is dropped over the throttle lever and the other end is looped over a cup holder to the rear to prevent the throttle from going too far forward. The key is to do something as a reminder that it is in use. I've seen others wire a red light to the top of the helm area.
