Very informative, wasn't expecting so much of your research. Thank you. This has been very helpful. I now have it all put together & running great. Seward, Ak. bound Sunday for a Halibut test drive. I feel confident ,from all the help with this out drive I have received, it will get me out &...

Most excellent information, this I can understand. Thank you.

What is the gear ratio compared to? If there is only a gear ratio in the lower but not the upper, what makes it the right one/ compatible ? Is it determined by the engine size or?

I did read it but I just wasn't 100% clear, due to alot of prior misinformation. Thank you for the clarification. I will correct a couple of friends as well.

Very good. I already changed the bearing race & shims to match. I am using Valvoline 75/90 in my out drive. Is that ok?

Yes to all the questions. Did a total switch to marine. This Hp information is appreciated, not here to argue. My question is, can a 280 tranny work on top a 290 dual prop lower. Yes or no. Thanks.

Thanks, I understand the lower 290 is a stronger/ heavier unit. Is the 280 single prop tranny , as a lighter gage tranny ok to run on top of the 290 dual prop lower?

I have a 350 vortex engine from a 1 ton chev. Van. Mechanic friend explained being such, delivers more HP than the Marine application motor, usually not more than about 270-280 hp. I'm not a mechanic, still learning. Advice is always appreciated. Thanks.

I have a 280 tranny and a 290 lower. Can these two be compatible with each other? I'm running a 350 vortex engine w/ approximately 340 hp. I believe the answer would be probably not. What's the verdict?
