Valero YT Setback
Randy,
I recently purchased a 1988 Valero YT, open bow, with an 85 model Evinrude
235 engine. I got a good deal on the package due to the fact the
engine has a bad piston. I am not the biggest fan of OMC products
but plan on repairing what I have to get me on the water ASAP. I
have a couple of questions. First, what is your recommendation on
the amount of jackplate offset you should have with this package. I
measured the current jackplate offset and got approx. 9" between the
transom and the motor bracket. This seems to me to be a lot of offset, not
to mention a lot of strain on the transom. Since the engine was
damaged I was unable to test drive the boat. I knew the past owner and he
said the boat would run around 80 to 85 mph. I am not looking for strictly
top speed since the boat will be used to pull skiers as well. Also,
do you have any OMC parts suppliers/dealers you would recommend? I
will be needing pistons rings gaskets etc... I recently signed up to
the registry and just wanted to say the website is great!
Thanks,

Shane,
I, myself, owned a Valero YT bowrider in 1987. Had a 225 Yamaha on it at
the time. My best friend had the same boat with a Johnson GT on it. So my
recommendations are going to be based on all the testing that we did. I
found the best overall setback at about 7 inches. Because of the bowrider
area, I don't think the 9 inch jackplate will hurt you. I tried 9 inches
back then, no gain - no loss. 80 - 85 mph is almost exactly what our boats
used to run. I would try to run a 27 pitch OMC SRX and have a lot of roll
put in the leading edge. This will give you a great hole shot for pulling
skiers and the top end that you are looking for. Sit the prop shaft
centerline around 1 1/4 inch below the pad and that should put you right
in the game. I get most of my OMC parts from Pro Marine in Bradenton, FL.
Their phone number is: 1-800-621-7761. These guys have virtually
everything and are really great to work with. Good luck with your project
and don't give up on the OMC yet.
Randy
