Here is a picture of the low water pickup that I am going to install on the center lower unit. I hope it works to fix the overheat problem. Will keep you updated next week with next sea trial.

Twin O/B Sonic

Awesome stuff Craig! Can't wait to see it in person.
A cooling trick I use on O/B's jacked to the moon is to plug the top 1/2 of the water intakes. This keeps the pump from cavitating and forces it to pull from the bottom only.
Motors are high enough on this Sonic that w/same set up as last one it struggles to bite hard enough to plane but does not over heat once up.

Call Hydromotive 330-425-4266. They used to make a low water pickup nosecone that worked great.

Scott is very innovative, I plan on having it installed this week , weather permitting.
I went as Crockett, We had a Blast over there, weekend goes by way to fast, I was there from Thursday morning till today. We had a great crossing both ways. We got lots of Lobster, freezer is full. Sundance Marine does a great job on making sure everybody has a good time & the goombays were flowing. I will keep you updated as progress goes this week.

Another attempt at solving overheating problem on center engine, not solved yet but engine not overheating at 4000 rpm's but soon as you turn up the rpm's with engine trimmed all the way down, temp starts rising. Rains have come & washed out the rest of the day, doing some work on the trailer, leaving boat in the water overnight. Taking a gps with me tomorrow morning to get a speed test. Will keep you updated tomorrow.

I sea trialed boat this morning 74.6 mph gps. I am happy with the speed so far. I need to find some more props to tryout. Still having overheat problems, But discovered after pulling boat out of the water that the low water pickup that I installed is blowing out the silicone and letting the water to bypass it. I guess there is alot of pressure there. I have a set of miracle plates to install. That is the project for this week. Will keep you updated on next sea trial.

I just got done installing miracle plates on center engine & filled in top holes on outer engines. I will sea trial tomorrow . Hope for no more overheating problems.

Still overheating with miracle plates. I ordered a transom pickup from BOBS MACHINE SHOP. I just got done installing it & running the hose to engine. This should solve all overheating issues. Water test in the morning.
