Well, I got a job now, so Ive been thinking about buying a new boat, maybe a Donzi 16 or 18 classic with the 350 already installed.

What about this

Then exhaust, water crossover pipe, prop, drive shower, and I think that will hold me over from may till june, then what would I do to it first?

How quick do you think I could go on 325HP with a 1.84 or a 1.5 Alpha??

325 HP should put you in the 60's with your hull. I just got a Hot Boat Magazine and the Land & Sea Stern Jack is on sale for like $1450 for the Alpha. That would be a really cool way for you to get some performance out of your boat and you can leave the motor stock for re-sale and reliability purposes. Just another possibilty. The V8 engine replacement just seems like a very large undertaking that will be very costly. Keep us posted on how you are coming with your project!!

What about an 18 donzi with a BBC?? Is that factory??

nope. biggest you could ever get from the factory in a donzi 18 was a Scorpion w/ bravo, a 23k upgrade.

What do you think I will need for the 350swap?

Mounts
Fuel Pump
carb
flame arrestor
exhaust
headers

...Oil cooler, Powersteering fluid cooler, Ignition system(distributor, box, wires, plugs), throttle linkage, remote oil filter, coupler, a hose from the oil drain plug for oil changes, probably oughtta go with some extra gauges, like water pres, oil temp and fuel pres. 4" exhaust hosing, and a bunch of time to rig this dude. Can't think of anything else, but I know there is more. Not sure how much is inlcuded with the motor package purchase you are looking at. Don't be intimidated, it's fun stuff. Goodluck.:)

sounds to expensive on a high school budget.

I think I will rob a liquor store :D

Tell me about it, I rigged mine last year. You will get nickled and dimes to death. It's all worth it in the end.......:D

Rob one that sells lotto tickets.....:D

I saw a 210 sport for sale in NY for 3,995, 350" 260hp, trailer and stand, cover, alpha 1, 1/4 swim platform, what do you think?
