Lehman 225 high idle only even warm?
Hello all. My new to me boat has an odd issue. The idles when cold are 500-600. The starboard ending actually shakes at cold idle, as if the idle is too low. I usually bump the throttle up just a hair when cold to calm it down. I usually let them idle for a 5 minutes or so before leaving the slip or anchorage. They never try to quit when going in and out of gear.
But once up to operating temp, both idles are right at 1000 in neutral, but drop to 700 ish in gear, but they clunk more than I’d like going in and out of gear.
I’m thinking of lowering the idle when hot and just dealing with a low cold idle.
Anyway, just wondering if this is normal to have such a difference between hot and cold idle.
