your top cap bolts are glowing red :D :eureka:

Re: So.... Do You Shower ?
 

The pic of the shower, isn't it suposed to hit the top cap and run down? Looks like it is missing. I don't have them 1:36 B1s, no chaulk at all, I step on mine to get in so they would be in the way.

I have Billet Marine topcaps with internal cooling passages
on XR upper with Sportmaster shorties/5blade props.
I've made some heavy passes and see no signs of high temp
on the upper.
The sides of the upper look like new with no lime buildup from higher temps.

Dennis, my drive look the same. However, I've got 2 new IMCO showers in a box I just recieved from Trick Marine. ( Thanks Fred) I got a killer price and I figure it's cheap insurance.

I use the billet top cap design from Innovative Marine. I also think the top cap design helps to strengthen the top cap because it is bolted to it, thus making it harder to flex. That top cap deflection is what causes some drive failures.

I know a person who works for Merc and he says that on XR the best
addition to the drive is to replace the factory topcap with a billet cap.
I went with the Billet Marine because it also cools the drive and looks trick!

Sure doesn't sound like heat is a problem in drives.

Re: So.... Do You Shower ?
 

i'd probably put my money on bearing preload and gear backlash... the tighter it is the hotter it'll run...

i'd track temps over a period and see if there is a trend of temperature lowering over the season as she gets a few hours on her...
