You should be proud. It looks great and solid. Plus you both spent quality time and achieved something tangible that can be used for years to come. Your first restore is great

Thank you for the info... I am going to talk to a buddy of mine who is into all of this stuff and see if he has one.. If not, I'll go make the purchase

Johny25, thanks for imparting your knowledge. I've read numerous of your posts and I know your knowledge of these motors is extensive to say the least. This is motivating me to replace the prop on my engine. You say that you need the RPM at top speed with current prop.. How do I go about...

Good to hear from you too... I'm using a 10.5 inch 3 blade, which needs to be replaced... I think that the motor can take an 11 inch prop but I have to do more research on that. I have a kicker motor , a 6 hp on my boat that I use for trolling and sometimes when I am going long distances i...

Awesome! I'm glad that it worked! I couldn't beleive it the first time either. Try this to get over 40km/h: 1-clean and wax the bottom of the boat 2-make sure your prop is in great shape 3-a dolphin on the bottom of the motor might help Was your wife happy??? THat's the most important thing

HI Siguz, I feel like a bit of an idiot because I didn't read your original post close enough when I replied. I guess I was in a rush... So now that I have time to sit down here is a proper reply. You have the exact same motor as me other than the electric start! Amazing motors , they are...

haha that's awesome! well one benefit with the extra speed is that you can get out of rough water situations faster, or conversely, enjoy them that much more!

That is pretty great improvement - 33% on speed! And probably a whole lot less frustration with the boat planing quicker I bet... Although the fuel consumption would be higher, who gives a **** when you're having that much fun! wooohoooo

Joe, the pontoon Idea is amazing! Congrats on fixing that problem. That is some awesome fabrication and thank you for sharing it. I think it's a great idea. Looks like you used pvc sewer pipes with endcaps glued on for the pontoons. How did you mount them to the boat? L brackets riveted to the...

Thanks Ronnie, and welcome. Did you make any progress yet??? Your boat is going to be amazing when you are done with it - I can tell, because it's already pretty awesome!
