454 Magnum Upgrades

I have been told they have problems with higher HP and have to be shifted like a crash box????.

Well, now someone with some serious real world experience running one will tell you different

I ran 575 hp spinning 31's thru 1.50 gears and never had any issue. Yes, it does shift a little hard due to big props and solid bite but it always shifted. Not really any harder than a 1.34 Bravo with a big wheel on it.The efi catches the engine load and prevents stalling. I did install a neutral switch over ride so I could start it like a crash box but that was by choice. If we got stuck just floating around for a while at a poker run stop, I would just shut it off in gear and refire in gear, no waiting for the EFI to let the idle come back down.

If I didn't build a 900 for my boat, I would still be running the BH drive.
Great handling, straight tracking, good slip numbers ( under 9% ) and of course, a sweet rooster tail The BH was on my boat when my avatar pic was shot.

It outlasted bravo x drives by miles too. 160 trouble free hours compared to 20 to 30 out of bravos. I wouldn't hesitate to run one on a light boat with 600hp.


PS, I picked up 8mph over a B1X.

Thx, for the info...the feedback I got was from someone who has tons of experience with them; and runs one.

Just my opinion Tom and you know what they say about opinions

Yep, always two sides to the story..thx again for sharing your experience; much better than the "somebody I know". Still think the Arneson would provide the same benefits???
