lower unit

[stcroixx09]

looking at replacing my lower and upper unit on my 1975 24' regal. found one online at gomarine for $1295. two questions i have are 1 does anyone have knowledge of them and their products? says 3 year warranty seems legit to me. 2nd they offer 4 different gear ratios. do i need to find out what mine is and stick with that or can i use any of them. if any of them which would be best. i believe some gotta be better for trolling and others for top end but im not sure which is which. is their a happy medium? any knowledge would be appreciated as all i know for sure is my lower unit is cracked and the jb weld aint gonna hold forever lol. thanks in advance

I bought an after market drive from these folks years ago for the fourwinns.  10 years no issues  http://www.sterndrive.cc/

 

the gear ratio needs to be the same and it relates to the HP of your motor.  you adjust high end / low end speed with the prop pitch.

you need to get the ratio for the engine you have. I think the ratio for a v-8 is 1.50 to 1. you should be able to contact them and tell them what engine you have and they can tell you what ratio you need.
