Please explain I'm sure I don't get it. Why would I want to dump less fuel with I'm gonna assume less of a cam? Wouldn't I lose power then? I'm not sure it just seems like it would?

Alphas must go if you plan any engine upgrades.

I agree alpha drives will not hold up in a heavy boat. Are yours white? The other hold back you have is exhaust on the pachangas

Mine are black were replaced like 90-100 hours ago . What the problem with the exhaust on the pachanga the manifolds or the rest cause I'm pretty sure it's all 5 inch after the risers

So what I'm getting is unless I want to repower and find a steal of a deal on bravos it's not really worth it to try with this set up. Maybe I'll just try going up a prop pitch and see if that makes me feel better haha

Lugging the engines puts more stress on the drives. So, really not wise.

If looking for more prop performance see what the others are using for props (Manufacturer, Model, Diameter, Pitch , etc) with success with your same year/make/model/engine/drive equipped boat.

what i was saying in post 19 was you are already flirting with the breaking point with these drives. and more pitch will also stress them more as SB says. i am surprised they put alphas in an 88. i guess they probably had a hard time keeping up with demand for bravos in the first year of production. best way to get a pair of bravos is to shop for parts hulks over the winter. pick them up for a grand, sell trailer for 500, scrap hull for 100 and get another 100 back in aluminum and scrap engine weight. might even find somebody wants the hull for free.

And don't forget that if you do a straight Alpha to Bravo swap, you end up with some new issues. For instance, although your new drives will handle significantly more power, the Bravo gear cases have greater hydrodynamic drag than Alphas. That means you'll need more power to go just as fast (or slow) as you're going now. Then when you add more power, you'll find that the Pachanga hull wasn't built to take much of a pounding anyway. Translation: Sell the Pachanga as is and buy a faster boat.

If you truly have a nice 300 hour boat in good shape enjoy it and save money for gas the boat has an Excellent hull and handles Great in rough water. The boat has alpha drives because the bravo came out in 1989. Last these boats like mirage plus props. Contact Brett at a blades you can prob pick up a couple mph by changing props
