Still working on getting interior pics. I haven't had a second to go visit with her since I put her up. Forgot to mention...and I regret not getting a pic, but I had a real nice fella backing his 24' Attwood down right next to my 22-2 last week in Apalach. I knew the reader's digest version of the history with these two but he knew a lot. I felt like a rockstar at the ramp with all the old salts coming over to check her out and giving thumbs up!

Beauty!

Aaron,
What style rub rail did you put on your flatback?

i believe this is where i ordered mine from. if you order 70 ft, you'll have about 8 ft left over if you wrap it all the way around the transom

Hey guys,

I need to make a prop change on my F200. My in town dealer set me up with a 14.5 diameter 16 pitch 4-blade Power Tech. The boat accelerates well out of the hole but vibrates pretty violently until on plane. I called Power Tech and he remembered talking with my dealer and the details of my boat. His calculator told him this was the prop I needed. At WOT I am only achieving 4800 RPM and about 38 MPH. My throttle connection at the motor is correct and travels stop to stop. The PT dealer says those number show 90%. She does have a nice smooth cruise at 4400 RPM and about 28 MPH. I need some other opinions because I don't know what kind of calculator he's using. I was thinking realistically mid 40s at WOT. Cant afford to hurt this motor...

Thanks,
Edward

At 4800 RPMs you are not achieving the top RPMs, based on that prop you need to go down in pitch. But I believe that motor should be able to handle more pitch. Aaron is running a 17P Enertia Eco on his flatback with only 150 hp. Have your reached out to Ken at Prop Gods?

I agree it sounds like you have too much prop. Also where is the anti cavitation plate riding while on a plane?  It should be on top of the water.  Also you want to confirm your tach is reading right.

something is strange for sure, those numbers are way off. im turning a large 16x17p with my 150 and bottom paint and have been able to get 5600 rpm 42 mph and turning 3600 doing 28 mph... are you running with the porta bracket all the way down or are you raising it up after your on plane? just raising the motor an inch or 2 can bring the rpm up a couple hundred. also, which powertech prop are you turning?

[HawgLeg]

Looked back at the part number because I wanted to confirm what I told y'all was correct. The prop is a PTZ4R15P which means it is actually 14.25" diameter and 15 pitch.

Aaron, I was running the bracket as high as I felt safe for the motor ( until the water pressure sensor I ordered comes in). Cavitation plate is above water on plane. I installed a Yamaha 6YC display so all engine data that I'm reading would presumably be as accurate as it can be. Wile at WOT, I've fine tuned motor height and trim in fresh and salt water, full tank to 1/4 full, live well full and empty, passengers on board and by myself. Your obviously running much more prop than I am and if anything I would think with 50hp more I could turn a little more pitch than your prop.

Did you ever get your prop issues straightened out?

[HawgLeg]

Feels like forever since Ive been on the forum. Ive been out enjoying my boat. I have plenty of little projects left to do on her (rubrail being priority). So far my numbers are 5000 WOT 45 MPH. Best cruise is about 3200 at 28-32 MPH getting 5.5 MPG and GPH. That's a lot of range with 69 gallons on board. She definitely performs better  loaded down rather than with just me and the wife with not a lot of fuel. Trim tabs come into play when I'm under a 1/3 of the fuel tank. The F200 gives me plenty of power where I need it. Still havn't put her on a scale.

One thing I wish I had done is a water trough at the transom. I use kayak scupper plugs and they work great but it takes a little work to get all of the water out the back. Not a one man job.

Overall I'm loving my setup! Shes offshore worthy on calm days and has braved 25kts straight east in the keys. Glad I overbuilt her a bit.
