I'm looking at a couple different options of drive showers for a stock Bravo 3 on my express cruiser (not gonna be setting speed records)... Its still using the thru-leg cooling setup for now..
Given that its still being cooled by water inside the drive, is there still any benefit in my situation to add a drive shower? Personally, I like the look and simplicity of the sport tech cap on Hardin so leaning towards that, but I just wonder if its overkill for me.

Heat is the #1 killer of drives outside of abuse, showers are always welcomed

This is cheap, might not be the best. Pair this with the Simrek drive shower for good measure. Clean overflow bottle out real good and monitor it for burnt fluid. As you know. B3 drives run pretty warm and as said heat will a big contribution to killing it. Pick your flavor of Lube.

I waited a long time before getting mine installed, but finally did with no regrets. My drives stay cleaner and ditto on the heat/cooling benefit. Yes worth it, I'd do it again. Baja 35 Outlaw with twin 525s, Bravo One Sportmasters.

I put a Simrek shower on my Bravo 3. I feel it helps keep it cooler

I assumed the general consensus was "yes, worth it", but I was just curious if anyone had any "hard data" that shows how much it lowers the temp of the drive oil.. If I was super motivated, I would consider trying to figure out how to get a thermocouple inside a drive to measure lube temp lol, but I'm definitely not interested in drilling holes in my drive..
I'll definitely be looking to pick up one in the near future.. I'm still leaning towards the sport tech from hardin.. I really like how low profile it is.

Their website is very old school.
but you want the Max Machine Worx drive shower. Best product out there.

I run this style plus a -12 intercooler dump on top the drive............shippy I think you are way over thinking this

The IMCO is nice and works well

Oh, im 9000% overthinking this lol... but i cant help it.. thats just my engineering brain trying to get to the bottom of it... I see so many marine doo dads and gizmos that are the next best thing cuz I think a lot of boat owners are suckers, so I try to do my research before opening my wallet.. lord knows boats keep wallets light as it is
