Boat Builder Central - Builder Forums

.....launching the rebuild 24.11.2012

..a GF16 reinforced for rough conditions.....
....transom knees 2 to hold the new 4 stroke in place
...with a center console located to 80% at the midseat
...skipper has to stand behind the cc
...installed engine 25HP 4stroke Suzuki
...rebuild of the rear seat with waterproofed homemade hatches

...it is fast on plane

I followed your thread when you were building, I thought your boat was built like a tank to begin with!
Nice build Bernd.

Looks very nice, Bernd How fast is she??

That does look nice, Bernd!

Thanks @ all !

About speed I actually can't say how fast it is because of break in time. I'm not allowed to give more than 3000 rpm in the first 2 hours.

On Saturday I drove 2,5h. I will inform you then the break in time is over.
(A little movie could be made )

Here the next pictures from the 5. hour break in time....







..movie is coming soon....

Congratulations, Bernd! Nice job!

Nicely done, Bernd!

Really fine rebuild. Bet she fly's like the wind with the 25. You'll like how quite she is and the maitenance is much less. John

Sweet! The GF16s are some great looking boats, and that one is nicer than most

Thank you !

The video is finished but I have trouble to upload it to imageshack or photobucket. The origin video has abot 300 MB and the resized 80MB.....something does not work. But soon ..I hope.

Super job, Bernd!! Great looking GF, the white really shows her off. Looks good moving through water. Let us know performance information once you get the motor broken in.

Keep on Buildin'

Robbie

Awesome looking job Bernd. Do you have any idea how fast she is with the 25??

Hi @ all,

I tested the boat without a hydrofoil and with the wrong prop (I believe) . The wrong prop means it has a pitch of 11 and the rev limiter showed me 5700 rpm instead of 5200 Suzuki says.The engines cavitation plate is about 4,5 cm below the keel line.

With this hardware , 10kg battery, anchor 6kg, 25litres gas stainless steel hardware (about 10kg) me (90kg) and my daughter (50kg) 5kg soft drink boat weight (about 210kg) .......upstream 20mph.

Next test is with the SE200 with sport clip. After this with another prop....12 or 13 pitch.
A Suzuki dealer told me that the standard prop with 11 pitch is there because of design for heavier boats to come out of the hole. For my boat it has too low pitch. The phenomenom of the rev limiter who displays 5700...5800 was discussed here:

I'm sure then I have changed my prop the Gf will go very fast. BTW this engine has a nice sound and the fuel consumption is very low - not comparable to my 2 stroke monster. I was very surprised of the torque of the Suzuki Df V Twin...quite good ! The electric starter is a nice feature too....just a part of a second and the engine works.

I'm happy with my Suzi.

Looking good!

I know this is a slightly older thread but would you mind sharing a few closer pics of the center console? This is something I'd love to do with my GF16 build.
It appears you were able to keep a hatch in the middle seat?

Sorry for the late reply - I was offline a lomg time. The first I did: I used cardboards to design the dimensions of my CC. I wanted to have good propertion CC to boat and the max space between the sides and the CC. I will take photos with dimensions the next days . You will then be able to copy or to use as an idea how to construct your own one. I first used a CC-design from here and then I cut the cardboard and decreased with the cutter more and more until I was satisfied. To hold the pieces in place i used duct-tape and zip ties .

Hope it helps you a little bit.

Bernd

Okay, here is the link to the pictures...

BTW : I made the CC removable - that means, I used stainless steel brackets and screwed them to the CC an to the midseat - if I sell the boat once a day (but I think that will never happen ) the new owner could remove the CC and use a tiller engine.

Wow! Thank you so much! It is greatly appreciated!!

No problem - thats my understanding of a message board -to help each other.
It would be fine if this would happen all over ther world - a lot would be much easier and less complicated / even more relaxed for everyone.

Keep on build an have fun !

Fishing / Boating in France:

BTW: I never felt unsafe in my GF16 - I had sometimes bad weather and rough conditions with waves of 1,5metre - I just had to slow down and to move very slow - but never one drop of water inside. The best flat bottom boat construction I ever saw.

If you have questions , feel free and send me a message - Cracker Larry helped me a lot too !

Here is a movie from this summer:
