Still breaking in and building up RPM to motor, will have to reset idle screw and throttle cable in the near future. Motor is running wonderful. I'm running a 2 blade 11p prop. Engine was set at 2nd tilt notch and boat would porpus above 26 mph, re set motor to 1st notch and 50lbs sand bag in bow. All rides beautiful at right around 31 mph and for now that's about max. We're not at full RPM as of yet and will build to it. Couple tips you should abide by with these vintage motors. When trailering no transom saver due to if you tilt motors to far you can possibly get floats stuck then problems for motor. Breakin for a newly restored motor, run 25-1 for 1st 2 tanks of fuel then change to 50-1. 1st tank run throttle all over up to plane only no swift movements, 2nd tank can run to 3/4 throttle still move speed all around run WOT for only 1 min. When taking boat/motor out always run motor out of fuel. Due to ethanol in fuel use fresh fuel at all times unless you have access to ethanol free fuel. I personally use what I need and never store fuel for more than around 14 days. I keep a close eye on everything but if you have your ducks in a row should have no problems. Also I run 87 octane, I need to search around my place to hopefully find an ethanol free station close by. Always run the best oil also. Anyone ever has questions or needs help on there vintage motor just PM me all you need to do is ask, and yes there is never a dumb ? Just one that was never addressed. Will post more pics soon.

Out of curiosity what pitch, prop are you using, clearly a 2 blade brass. Sounds like it's propped pretty dead on from the numbers so far. Hopefully you will hit mid 30's once broken in. Looking Good so far. Do you know what your RPM is at WOT?

On my Zip I have a 1961 Merc 45 hp 400e. It has a 10" 2 blade brass prop. Was wondering if you could tell me how to determine the pitch it is.
Here are a couple of pics

Possibly clean up prop and markings might be visible. 1st number is diameter and the second is the pitch.

Not sure yet what RPM's Motor is turning yet. I have a tiny tach and will get some figures from there. That motor new at WOT should have run around 5400, I'll check and see what mine will turn but I'll be much more comfortable around 4900/5000 at WOT need to remember we're talking 50+ year old motors and want to keep em alive not blow em up! . On your 35A what RPM are you turning?
