honda 50 4-stroke prop

5 posts in this topic

My grandpa has a 50 Honda that is either a 2000 or 2001. I am wondering what the proper pitch for that motor should be, as it seems capable of very high RPMs (over 6000) and can't be trimmed very high before it starts sucking air.

The boat is a 16 ft. Lund Stinger with the wider gunnels.

Thanks for any info!

Do you know what you have for a prop right now, and do you know what you're turning for RPM's at Wide Open Throttle?

Based on your description I'd say a 15 or so, but it depends on what it's spinning now and how it's performing.

I just looked and want to say a 13, but it will do almost 6500 on the tach when wide open. It really seems the bow digs in and the stern is out of the water so that it sucks a lot of air if it's trimmed up much at all.

If that's the case you'll need to go up in pitch... 6,000 is your recommended top end, so I'd say you'll need to go up in pitch to a 17 possibly.. but I'd try a 15 first, if you can find a place that will let you try props out without buying them (or return them, as long as they're in good shape).

    • The past week has had me having multiple close calls and missing a brute at 45 yards.  Tonight I talked my dad to give it another try and there were birds in the field when we got there.  Birds ended up leaving as we tried to sneak in.  A short 20 minutes later they were back and we watched and worked the big group of toms and hens for more than 2 hours before we got one to commit.  Dad shot him with his 20 gauge at 48 yards,(this thing shoots an awesome pattern).  The 3 year old was down and only flopped a few times.   Nice 1+ inch spurs, 10" beard and heavy.  A good evening for sure!
    • Sorry to disappoint guys, but this tom was not my first bird of the season. Apparently that's part of the rules. The score won't count towards the team. I don't have any measurements for the jake I shot so we will have a zero from me.    At least my freezer is full. 
    • Way to  go 1957 !! Congrats!!
    • sugar is not a drug. 
    • Another good day today out on Superior ,,,, Had my first double and triple in the new rig today ,,, the day didnt start out with perfect weather but the fishing more then made up for it ,,, The mud  covers a lot of water but fishing the tea  colored water and edges of the mud paid off ,,, the cohos grew 5 inches  from eating this years smelt,,,, had some go 23 inches today 
    • Say no to drugs, like sugar.  Yes, sugar is a drug.
    • I won't be able to post the scores for this week until maybe Wed. so if someone else wishes to do so feel free to do it. In fact for the entire summer season I'm going to be pretty much hit and miss. So don't count on me the lake is calling and I have no computer there. My scores will drop like a rock unless luck prevails.
