Will all bravo 1 drives interchange,excluding the late model slope back.Some have oil resavors and some don't. I thought they would all interchange.from the 80's to the late 90's ?????? Thanks JOHN

Late 80' to early 90's did NOT have the oil reservoir ...You can convert the older TA to accept the reservoir on Some ...Depends if your Belhousing Has the hole for the Check Valve Setup ....on my 311 one Transom Assembly was good to go and the other one I had to replace the Bellhousing ...m

hi any body no jeff cropper from ny and how is his work live in massapequa looking for a engine builder thanks for any info

The late model "slope back" (not a bad description ;-) makes no difference other than possibly your particular external steering system. There are differences in the gimbal bearings and bellows sleeve to accommodate the larger u-joints that came and went in the late 90's early 2000s. Oil reservoir issues aside.
