Hi, new to the site, I have a 74 650 thunderbolt with tnt but a bad lower unit and rough runner. and a great running 650 that came without tnt. is it possible without modification to bolt the better run to my tnt setup???

Yes, there is an adaptor kit that makes it possible...the kit is expensive though!...I will see if i can find and post the link to the kit

If the good motor is about the same year as the one with PTT, you can always drop the powerhead and gearcase onto the PTT midsection.

Alternatively, I though the shocks on the non-ptt motor could be removed and the PTT trim cylinders installed. The inline sixes had PTT brackets the bolted to the upper shock mounts. The PTT cylinders bolted to the lower shock mounts and the PTT brackets.

Easily done, but with a few simple mods. You don't mention if either motor is installed on a boat or not.

Remove the two shocks from the good motor. Remove the two PTT cylinders AND brackets from the bad motor. Take note of the different hardware that is used, you will need ALL of it to install onto the good motor. Bolt the PTT brackets to the good motor. You will need to drill at least two (preferably four) new holes in the transom to secure the mtg brackets properly. Bolt the brackets to the transom. Install the PTT cylinders onto the brackets. Connect the four hydraulic hoses from the pump to the cylinders.

You will also need to remove the reverse lock mechanism from the midsection. It would be a bad day when the PTT system tries to tilt the motor up and the reverse lock is engaged. Not sure what would break first .
