I was plenty bloody when I did the fill hose on my Offshore. I feel your pain........

Flattered that my post was highlighted...........:)

After reading this I like my I/O more and more....... I built a 300+HP SBC in my driveway for ~$3.5K........400hrs and not a peep.

Thanks for the compliments.......pictures don't show the flaws.....:) Interesting take on installation w/o screws......... I put tape over the holes so they are already filled w/ resin. I may take the suggestion and leave the screws out.....I'm pretty sure the caulking will hold it in...

Finished product............. Like I said, it's not pretty but it's STRONG!!

Yea........feel like I got a jump on the spring, last year I had to wait until spring to do the other hatch. Now I can install it whenever the weather permits.

Got the final coat of glass on this morning.......will take pics of the finished product.

I cut the edges @ a 45* angle but I still think I got some air bubbles......I suck at this! It's not pretty but it will be strong.

I also used 1/2"

Installed the plywood and got glass around the edges today....

Cut the plywood tonight........hope to glass it over the w/e........

No problem......just wanted to point out gw204's method.......he's way beyond me!

When I install the new plywood I don't go all the way to the edge......maybe leave about an inch around the edges and put in a layer of mat. Check out the end of this thread where gw204 gives his input........ viewtopic.php?f=3&t=19451

Check out this thread from last year........... viewtopic.php?t=19969

Hope to get some glass on it before it gets too cold.

Removed the hatch over where the aux tank would be if I had one. It was very soft. The core just about came out in one piece...... Not bad for a couple hours of work.......

I like this prop.........seems to "grip" well. Also, I have vortec heads on my engine that supposedly adds ~30hp.........not sure if you have a Vortec engine. The intake manifold will have 8 bolts instead of 12 if it's a vortec.

This is the prop......the pitch is 17". http://boatpropellers.iboats.com/Mercruiser/240_-_300_HP_(All_Years)_17.00-Pitch_RUBEX_3_9511-148-17_Propeller/773/20407/?cart_id=400066424 i get 30MPH at ~3600RPM and ~40MPH at WOT (~4500 RPM)......

I am turning a 17" aluminum...don't think a 19" would work. Also need to know your OD ratio, should be 1.5:1.

I'd go back o the Gulfstream and renegotiate...........drop in a 383 stroker or build one with the bloc that's in there.
