Hey everyone I just bought the boat about a month ago and I’m ready to throw some money in it any up or down on the boat it got 305 5.0 gm motor last owner told me it goes pretty good I’m the water bum I live in mass and it cold so too I’m it out for a second when I bought it from him I see it has a 2 barrel carb was think on replacing the intake manifold with a edelbrock performance one and a wuartejet carb any body can tell me if it a good idea prop or no good anything can help thanks

Welcome aboard

It doesn’t sound like you did a sea test so I would wait to see how it performs as is before making any changes.

I m not going in the sea with it it most be in the river I live in mass so it cold right now to try anything with it but thanks

That's a huge motor for that boat. I don't think you need to upgrade the performance at all, it will already go way faster than you want it to. For prop, let us know what's on it now, but it probably came with a 19 or 21 pitch, depending on drive ratio. Do you know if your drive is a 1.47 or 1.98? Does your boat have smart tabs?

Sea test is a generic term to test the boat on the water. I hope the boat is in good condition as more than one person did as you only to find serious issue latter.

Guess you’ll find out in the spring.

To be honest I don’t know much about it or what rationit has but if u want text me so I can send u a picture cause I looo to see n it does show anything on the outdrive 413 328 0022

[Alexgomez-91]

It ran good I know about motors I’m gearhead just don’t know **** about boats plus I’m allready planning on changing both water pumps and maintainer on it so it should be ready to go in the spring

If the engine still has the plastic cowl cover on top the carb the engine and drive serial numbers are on it and you can look up the drive to find its gear ratio.

it
It does but the numbers r gone and can’t see them sucks

[jrsick]

I can't determine drive ratio by a picture of the stern drive. You may need to do some detective work with a flashlight and look for either 1.47 or 1.98 stamped somewhere on the drive. The numbers will be small font so it will take some looking to find.
At this point, outdrive ratio isn't critical. Take a RPM check at WOT and work from there. My guess is you will be going in excess of 50mph so be ready.

Sound like fun the past owner did tell me it moves fast anyways lol but I did some research n the prop says it’s a 14.5 by 19 I think that’s good

[jrsick]

The 3.0 1900 SR's came with a 19p prop and 1.98 drive ratio. My guess is that you have a 1.47. I put the over/under on your 4400 rpm speed at 54mph.

So I can imagen I get a little more after I change the intake manifold and carb I’m not trying to make a fast boat but if it run a bit better with a quadrajef carb then or what u think

[Alexgomez-91]

Oh n was wondering does these boat have a mechanical fuel pump and electric or what thanks

[mmwjr]

A 2000 would have an electric fuel pump. If she can do 50 mph as is I would not spend the money changing to a 4bbl as being a 19 foot boat the water will need to be absolutely flat to be safe running that fast or faster.

[Alexgomez-91]

Ok I see what u mean yeah that be scary to be honest but thanks for the info appreciate ur time and I was looking at the motor today n it look like it has a a mechanical fuel pump has well does that make sense to u or is that just a by pass

[mmwjr]

My boat originally had a 5.7 with a mechanical fuel pump and I thought it was the last year but boat builders use up old stock that can take a few years to deplete the old engines. The Vortec engines use and electric pump and have a 8 bolt intake manifold instead of the older 12 bolt.

I'd recommend against upgrading the engine at this point. Cheaper performance upgrade, for hole shot anyway, is a four-bladed 19 or 17P blade.
You haven't mentioned if you have Smart Tabs or not. Many people like smart tabs because they reduce bow rise during acceleration. With 17p four blade you may not need tabs because you would be up on plane in an instant. 17P would reduce your top end speed to high 40's, but that is plenty fast for a boat of any size, especially 19 ft.
