drop in outboard on stiletto

[rhengst22]

Yea I won't be doing any racing just SAW passes but don't wanna brake any more flex shafts.

Hey serpent can you look on here on OSE at the hyper performance 3.5 bullet drive outboard leg and tell me if this would mount up to a stiletto and what's the difference between this one and the use one. Thank you so much for helping me.

i dont know about the hyperpormance bullet drive , but i now OS will fit for sure and is better quality

I have run both the is unit and the proboat outdrives, to be honest I could not see a difference after I had done all the mods Darin says to do, and it really doesn't take long to do, and 1 of them I did to the os unit as well, I removed the Teflon liner and made one out of brass, less drag less flex breakages made for more speed. The only other thing I changed on the pb unit was the outdrive, I fitted the one from hyperformance and I still believe like this it was as good as the os unit.
Serpent I suggest you change your water lines as they are in the picture you don't have very effective cooling, I would have the line go to the esc first then into the motor jacket on the lowest union and exit out of the top one, this way the whole jacket is filled with water, plus its out in the open so is cooler by default, so giving the esc fresh cold water first its going to help keep it esc colder. Just my 2cents worth

Sorry, but I spent almost a year developing the Stiletto with Pro Boat, and especially took a lot of time to get that lower unit to function like a race-unit, but look like a scale unit... It's a KILLER unit, and functions great, especially if you take the time to blue-print it, as described in my race prep thread, here on this site. I COULD be a little offended by your post comments...

However, being that I have broad shoulders and don't easily take offense... I will tell you that the bolt pattern on the transom should match up almost exactly with an OS Lower... I'm not sure if the stub height will be able to be correct with the stock OS adjustment range, but I think it should be relatively close.

I think that a Lawless or other race style lower can be fitted if you use a Dubro 3.5 mount also. I believe the pattern should match up.

You'll save a bit of weight with different lower. The stock one weighs around 13oz, if I recall. I think my Lawless weighs about 8oz...

Have FUN!

Do they make a better lower drive for this Stiletto lower unit ? bearings? a better grease system (to hold more grease) ive been running mine for about 3 weeks a the prop drive is getting loose , looks like im am going to have to change it and did not know of a aftermarket upgrade.

hi Dave

My proboat outboard has been upgraded with brass liner with oiler and replaced the stock propshaft with the hyperperformance and it run much faster with the stock setup but I use 5s and surprise the stock 60A esc can handle it
