I've been keeping a secrete from you guys. Been working on an addition to the project for a few weeks. I'll update you before the weekend is over. Looks like this project may last more than 12 months.

12’ x 84” across the gunnel at the transom 24” deep sides at the transom. Roundish chines. I think it’s going to float pretty high.

Worked on the pad to mount my turbo sensor “TMAP”. I believe it measures pressure and temp. The factory appears to mount the sensor so that the air flow is thru the gap in the plastic across the red legs.Image

But I see that RPM has a turbo intercooler pipe upgrade and mounts the sensor 90 degrees different where the direction of airflow is not thru the hole. Does it make a difference?

I'll be honest I am not an airboater if thats what you guys call them, i have been watching this thread for a while now for the ecotec ltg. I am putting one in my 67 Volvo 122. You have the most detailed thread related to getting the engine running and plumbed and I thank you for that! I'll stay tuned.

Thanks for the compliment. That's what I was going for. Hopefully this will be of use for a while. If you need any details i did not include just ask. Got most of the poly put on my boat this evening and got the pad welded on the intercooler pipe for the TMAP. Headed to the camp tomorrow so no other progress this weekend.

Got the sensor pad put on. Had to order a bottom tap to get enough threads for the sensor retainer bolt. Should have it by Friday and I can test run it again.

And Merry Christmas again! I want to set my engine as high as possible to reduce thrust loss... ie tip of prop at the top of the transom. Any "rule of thumb" as to a maximum distance between bottom of boat to centerline of prop? Boat length and width and amount of thrust produced would play a big part in this number for sure. Just looking for experience and heresay :D . Or maybe distance is not that important because trim adjustments can cure all?

If you do research I think you will find you mount the engine as low as possible for maximum thrust. Having the tip of the prop below the transom does not lose any measurable thrust and having the engine lower gives it a much better push point.
