Re: Cheap bad idea
 

You have issues with fuel? Or plugged carbs? I will do a teardown next week, but was wondering if you have insight on the F100.

YZ - 27 is moving real nice for a F100 . . . What prop are you running? I have a buddy with the same boat . . . we've swapped motors a few times 175 merc, 225 Yamaha, now 200hpdi . . . the 175 only pushed it about 33/34mph.

Fish:
The only issue ive had with the F100 is gummed up carbs. If you dont drain the carbs when its winterized you will need to break them down and clean them. I never let gas sit in them for more then a month without being ran. As long as i drain the carbs at the end of the season it will start up first crank in the spring. It has been a great motor and never left me stranded.

The only other issue is i had a voltage regulator go bad on it. Not bad for a 12 year old motor. Besides the voltage regulator only plugs, oil, gear oil, and the occasional water pump.

Bigshrimpin:
The prop on it is a aluminum yamaha prop. Its 17 pitch and i believe the diameter is 13.25"

For only 100hp on a decent size 23' boat in happy with the performance. Even if i run it around 5000rpms ill get close to 5mpg.

The sea ox i have is the 2300 commercial so its probly got a lot less weight then the 23 in your picture. The only weight is a small wooden cabin in the front and lots of waterlogged wood.

my uncle also has a seaox 2300 (same year as mine) and he put a small center console on it. With a F150 i would guess his goes upper 30's.

Where I started: (I added a kicker and GPS since this pic)

And the next project:

I bought this from someone's unfinished project. I had to finish the last 30+ feet of TIG weld. Thankfully 5086 welds nicely. Probably going to do some stuff to make it lighter

With a full transom.

keep us updated

btw is that your trailer license plate on the kicker mount?

Re: Cheap bad idea
 

For the tow home from the previous owner, yeah.

Re: Cheap bad idea
 

I cleaned the carbs and it idles fine and runs ok. Needs a sync. Kinda boggy. Might go up a jet size.

Motor has good compression and is timed right and it seems I am close to having it run decently. Right now it bogs coming out of the hole. Yours do that?

I up sized the jets my motorbike and I like the throttle response on that. About 10% worse economy. A little over-fueled when it is hot out.

Oh yeah, that's a 20 foot master angler, not a 23. The pic angle makes it look big.

Re: Cheap bad idea
 

Unless i throttle up really slowly it always bogs when going from idle speed to a plane. Kind of annoying but it runs fine at all rpms so i just deal with it.

i knew you had a 20 MA i meant on my 23' seaox i think the F100 preforms pretty well. Im interested in the performance numbers with the F100 on your 20 MA though

Re: Cheap bad idea
 

Well, there are at least 2 published main jet options for this motor (125 and 128), so I might try the bigger one, and will proobably mess with the pilot screws to get better off idle performance. If I find a good recipe, I will let you know. Based on your input and Fr. Frank, I got a prop with modest pitch- I think a 12-3/4 x 17P to start.

Re: Cheap bad idea
 

looks like a pilot screw adjustment might be in order?
