Spoke with Glendinning. Common problem. Retention pin. Snapped cable or a plastic part on the MASTER throttle. If it were the slave, the rpms would go to max. Mine goes to idle. I'll let you know. Thanks.
Has anyone had experience with glen denning repairs? It stopped working on the sea trial. (Operator error.) And now there is a whirling sound coming from the throttle housing at the helm.
