anyone have a 470

[wellcraftv20step]

looking for a 470 mercruiser to repower my 89 v 20, please let me know if anyone's got one, thanks john,

[spareparts]

don't know how to get from there to you, but I know a guy n Texas that has a complete 4.3 motor/transom/drive for sale(you probably get the boat to go with it) pretty cheap. The boat was running, but the floor and stringers are bad and he decided to sell the parts rather than repair

[wellcraftv20step]

thanks spare! i think i just found a 1989 470 Pa. lake engine where i am on long island, just sitting here getting up the nerve to pull the trigger on the deal. this guy did a swap for a 4.3 and thats how he came about this engine. what i like about this deal is that the guy i'm buying the motor from is going to install it for a winter price and says he can sell my 3.0 with no problem. just thinking aloud,:nice:

[spareparts]

you should replace the gear ratio in the drive when you do the swap(1.98 to 1.84), but that being said, you will probably be fine just swapping props, try a Mercury Mirage prop to hold all that torque, go up at least 2 numbers in pitch from what you are running now

[wellcraftv20step]

thanks spare. what prop should i use. i am runnig a 15.25 x 15 with the current 3.0 motor, thanks,

[spareparts]

17 mirage would be a good start

[wellcraftv20step]

thanks spare. i finally got up the nerve to pull the trigger on the deal for that 89 470 mercruiser from Pennsylvania. i am bringing my v to him on sunday. who knows with the weather we are having in new york i just mite be able to give her a try at the end of the week. very excited to see the difference in power from the 3.0 to the 470. spent a year putting this boat togeather and was very dissapointed in the power. cant wait. thanks again for the help,

[spareparts]

89 model should be a a 165 or 180 3.7L a 470 is an earlier model with the small heat exchanger and forward coolant reservoir. Do you have any pics?

[wellcraftv20step]

the motor i'm told is an 89, same as the boat. i will do pics after i'm totally done with her this spring . after the engine swap all i have left to do is glass and gelcoat a cover for the fuel tank , as of of now it is starboard and as we all know no caulk or silicone will adhear to starboard,i only found this out after gelcoating the deck. but yes plenty of pics will be posted Spare!

[spareparts]

on an 89 engine, the coolant reservoir should be part of the exhaust riser, the exhaust manifold should be made out of aluminum, while the exhaust riser/reservoir is cast iron. There were some early issues with the gasket leaking into #4 cylinder. It would be prudent to pull the spark plugs and do a compression test on the engine. Also look at the heat exchanger, it should be 4" in diameter, earlier ones were 3". Take a good look at the charging system, its built into the engine balancer, look at the windings behind the balancer to see if you can spot any corrosion. While you have your head down there, look for signs of antifreeze leaking from a small hole right at the base of the front timing cover, its a weep hole to allow coolant that has gone past the cam seals to leak out.

That fella Spare can sure can save yo a$$.

[wellcraftv20step]

Spare i am familliar with the weep hole thanks, i will look closely for other probs, by the way i didnt like the inconsistancys in talking to the seller so i gave him the boot! i found another i am looking at this sunday in P a . it is a lake engine and comp is 125 across the board. What do you yhink of those numbers . you can take a look if you type in your search, craigslist Pa 3.7 mercruiser, its the 4 barrel .please let me know what you think he is going to run it for me on a pallet

[spareparts]

post up a link, I couldn't find it, what city?

[wellcraftv20step]

http://philadelphia.craigslist.org/boa/2801825407.html here you go spare.

[spareparts]

looks pretty good, it appears to be what he said it is(correct heat exchanger, manifold, etc) notice it has the complete power steering assembly, if your 3.0 doesn't have power steering, it would be nice to add. First thing I'd is add a pertronix electronic conversion, see if you can find the tall flame arrestor as well

[wellcraftv20step]

thanks again spare. i will let you know how it goes !

[twhrider2]

The 4 barrel carb. and associated components are worth over half the asking price! Good looking engine, good luck.

[aussie]

if would be good to let us no the difference in power from the 3.0 to the 3.7 i have a 3.7 and wasnt to happy on the engine power and buy saying that i stepped out of 17 ft with a 115hp so it a big jump in size and wieght

[wellcraftv20step]

well, i went to pennsylvania this morning to look ,at an run this motor. this thing ran perfect so i bought it. and the pictures did not do it justice. very clean.. happy day!. and aussie i do believe thier will be a significant difference. thanks for giving it the nod spare. i will put it in in march sometime.

[wellcraftv20step]

does anyone know where the purple wire goes to from the coil on the 470 mercruiser 4 barrel

[smokeonthewater]

can't remember colors but coil possible coil connections are B+ on pos. and dist, tach, and shift interrupt on neg.

If that feeble answer doesn't cut it and someone else doesn't pop in with the answer I can find my books and look up a better answer for ya.

[smokeonthewater]

Well I got curious and looked... my FSM's don't cover the 470 so I grabbed my Clymer manual and read a bit in the basic section.... If the wire is on the POS side of the coil it could the excitation lead for an alternator... does the engine HAVE or has it HAD an alternator on it?

[wellcraftv20step]

i am hopeing to compile a list of does and donts to remove my 3.0 engine and install my new 470 in my v. although i am not a mechanic i am going to give this a shot with a buddy of mine who has done it before, so help from the v20 gods would be appreciated. i do know i have to remove the drive. hey smoke, no it did not have the alternator. i will be adding one though ! thanks for the reply.

[spareparts]

electric choke coil on the carburator

[smokeonthewater]

I figured you'd have the answer Spare.... it's been quite while since I worked on anything with an electric choke..... I didn't even consider that

[wellcraftv20step]

Mr Spareparts to the rescue once again:beer:

[aussie]

did this boat ever get finished seems theres no happy ending to this:hide:

[wellcraftv20step]

I never did get that 3.7 installed aussie, i found traces of water in the oil and decided to have a friend change the head gasket that was like 7 months a go, as it often goes with friends it is still sitting in the same spot and i cant seem to get him to finish it which is really straining our relationship by the way! i also fabricated a new dash panel with new faria gauges and new switch panel that he has half way finished connecting, so i have recently decided to part my boat out which is a shame because i have done so much work to her . i am just disgusted as their have been more things go wrong with this project than is normal for 10 projects. it currently has a running 3.0 mercruiser in it and it is all up for grabs .

[aussie]

well i learnt a long time ago not to rely on friends even ones you pay i just do everything myself it takes a little longer but with the internet and good people on forums anything can be done my project is still on the back burner but hopefully ill finish it by next summer wild cat 3.7 lol

Naaaa... if you were in the stat4es I'm sure there would be a lot of ppl that would be helping out.. it's our nature

[cfelton]

You can change that head gasket yourself. If you have a Clymer manual it will help you through it. I would have a machinist resurface the head and maybe reseat the valves and check the valve guides and springs for you. I'd try and buy new headbolts as the ones over the exhaust side can get rusted up pretty bad, and headbolts stretch when torqued down and the heat over time reduces the strength of the bolt. Always go back and retorque the headbolts after about 10 hours of run time. Its really not that hard. I've rebuilt three of these motors with great results, they're really simple engines.
