Awesome engines ! First boat I ever owned was a 1985 Ski Nautique 2001 with a 351W. Engine was all original with over 3k hours. Ran like a champ. Out pulled my buddies malibu skier with a chevy 350 all day long. 351W is a torquey beast. Very cool engine, the PCM marine engines are reverse rotation or RH rotation. Awesome job !

[@halcobb1627]

A most excellent series that obviously took a lot of time to produce. Impressive attention to detail on the 're-fresh' (changing just the wear parts, not sure it's really a re-build). It's a shame there are so few views on your high quality video series. Thank You for making it.

[@westonzayd737]

i know im asking randomly but does any of you know of a tool to log back into an instagram account? I somehow forgot the login password. I love any help you can offer me

@Weston Zayd instablaster =)

[@westonzayd737]

@Chase Dexter thanks for your reply. I found the site thru google and I'm trying it out atm. Takes a while so I will get back to you later when my account password hopefully is recovered.

[@westonzayd737]

@Chase Dexter It did the trick and I finally got access to my account again. I'm so happy:D Thanks so much, you saved my ass !

[@chasedexter4975]

@Weston Zayd no problem :D

[@ecosubb]

Love this set of Rebuild videos. Amazing attention to detail and professionalism

[@martinwright3039]

that was the best engine rebuild series i have seen. It is a shame I can drop my 351 around to you for a rebuild.....

[@JacobVillemain]

Thank you!

[@ecosubb]

@@JacobVillemain Great Re-build project, thanks for posting. I actually have the same engine and was on the brink of trading it off and going retro outboard. After watching this I am more prone to doing a rebuild. That said can you elaborate on what would be a ball park number for a build like what you did on this one? [e-mail] Thanks.

[@ecosubb]

I'm literally in the same boat, have the exact same engine and on the brink of doing a Outboard retro fit. after watching this I'm gettin a hankering to rebuild this puppy...

[@millerso8]

Very Good Job Young Man!! Although I'm not rebuilding a Marine 351, I am rebuilding a reg. 351w for my '69 Stang. All of your "tips of the trade" and being very thorough will still apply to my build! Thank You for taking the time to share your knowledge!!

[@millerso8]

@@brandonknight7240 I don’t understand your reply??? 🤷🏼‍♂️🤔

[@prevost8686]

The 351W was a very good small block truck engine. Beefy bottom end, thick head castings, nodular iron cranks. 350 Chevy engines of the same time period had gotten so thin in their castings that heads and blocks cracking were common.

[@keithcheeks8536]

Very impressive, I have a Correct Craft Ski Nautique with a Ford 351 engine exactly like the one you just rebuilt. Thanks

[@peterstephenson9360]

I don't know jack squat about building engines, but I found this series incredibly educational and easy to follow. Out of curiosity, what would be the ballpark cost to a consumer to have you rebuild a marine engine? I realize that this was a pretty clean motor and most parts were still in good shape.

[@blakewilliams9642]

Awesome videos! thanks for the 3 part build.... Im trying to put together a 308 sbf for the second time. First time was failure with the wrong valve train geometry.

[@rogereivissa673]

Thank you for posting this video. I have learnt a lot of things.

[@lndnjiv]

Nice video!!!! And good looking engine. Cork valve cover gaskets hurt my eyes. Lol. Thanks for making.

[@JacobVillemain]

I love cork valve cover gaskets

[@ve3mzo]

you da man just like a pro it was a pleasure to watch this series thumbs up

[@rampagestiddies]

great work

[@jeffrobbins-phoenixarizona5348]

Nicely done. I have somewhat inherited a boat with the same motor in it. Signs indicate water has made it's way into the oil, and it's become clear i'll need to pull it and rebuild if it's ever going to function again. How much time do you think you put into the rebuild? I sure would like to have some of the equipment you've got in your shop, great set-up.

[@ronschriner2404]

Awesome video from start to finish. I have a 97 ski Nautique with 351 GT40 engine, and I need to do the same thing. This was very helpful. Something I was wondering, are all the parts readily available (rings, bearings, possibly pistons)? and are they available for the GT40 engine as well? I have found some things for the GT40 engine are hard to find. Thanks.

[@kevincates4682]

Nice work! I am about to embark on the same engine for an old boat. I cant believe I found a video so specific. Do you or anyone recommend a machine shop that could take care of the block for me? In Denver.

[@jeremyrios433]

Nice Job man! I have the same engine in my 72 Econoline 🤣

[@emeraldstevens8922]

Why not put a better intake on instead of that boat anchor?

[@maurice8033]

Great build! What cam did you use?

[@pieterdebel4605]

I have the same question!

[@rjbiz3639]

Awesome videos !!! Something that confuses me is setting the valves. Can you explain in more detail where you are setting the harmonic balancer?

[@JacobVillemain]

I use the I-C-E method when adjusting valves. When the Intake Closes, set Exhaust. Then use the inverse to set the intake; when the Exhaust Opens, set Intake. Balancer position does not matter using this method.

[@rjbiz3639]

@@JacobVillemain well thank you, very professional video and love your rebuild

[@joemartino6976]

Really impressive work. Thanks very much for the video. I'm curious. I have a 351 in my newly purchased 1978 F150. Out of the factory, I think these engines were rated at a little less than 200 horsepower. Assuming you're no longer constricted by smog controls, what kind of power power can you get to and still have a smooth idling/performing engine. Can it get to around 350 horsepower?

[@thomasceruzzi1871]

My marine 351W with GT-40 heads is rated at 310hp

[@wyattmerkel2040]

great videos, I need to put a cam in my 351w. I was wondering what cam you put in this boat? There isn't a lot of info out there and the forums have very contradicting information. When the motor is running the crank turns clockwise so i'm guessing it needs a regular cam and not the backwards cam. thanks!

[@kennethhacker1341]

I have had a lot of luck with lunatic cams...they are super helpful

[@itchy-scratchy]

What year was that Windsor. 70 -74 have positive stops on the rockers. No adjustments

[@jeremymartin3069]

I have this in my boat. I need to find an Alternator. Any idea what it takes?

[@blake_nivelt_389]

got this same engine and wanted your opinion on getting a few more ponies out of it. Was thinking of a cam, porting and possibly some gt40p heads? I'm no expert so curious as to what you think would help wake up this motor a little. I have the factory High output which only put down 285hp and want to get into the mid 300s

[@errbodyknowsdarules]

Assuming your engine is reverse rotation? You'll be limited on available blanks for anything greater than .460 lift and 212 duration on a flat tappet cam. Does the HO come with GT40 heads? If you're LH rotation, I'd skip the P head swap, include intake and aluminum heads with a hydro roller cam.

[@joelpalmer]

What would a rebuild like that Ford Windsor typically cost for 396 Chevrolet engine. Just a ballpark number

[@raymundo7687]

What shop is that, it sounds like i35 or i10 in the background lol

[@jeguim123]

How much around did all the work done to this engine cost to the client?

[@Bore_Punch]

What does a rebuild like this cost

[@owen.nibley432]

Whats your opinion on converting the flat tappet 351w to roller lifters? Is it possible? I have a marine 351w and thinking about looking into that conversion.

[@JacobVillemain]

I highly recommend upgrading to roller lifters whenever you can

[@billmongrain6094]

what sort of ring end gap clearances were you looking for on this 351w marine

[@JacobVillemain]

.020/.020

[@-fishhub-billydriessen1627]

What intake manifold did you install on this engine?

[@JacobVillemain]

The factory cast iron manifold.

[@EAS1325]

What size flywheel / tooth count does the marine 351w have?

[@JacobVillemain]

157 tooth I believe.

[@lvna8tive]

i thought marine engines needed stainless steel head gaskets

[@craigmclean8864]

how much did this rebuild cost and where are you located?

[@JacobVillemain]

San Antonio

[@ecosubb]

@@JacobVillemain Bro sure wish we had you down here on Miami. I have that same motor on my boat and would love to have you restore it. Do you recommend swapping out the cast risers for stainless steel? A buddy says he has one and may sell it. I'm also considering conversion to electric, been seeing some pretty knarly retrofits with forklift motors.

[@belledetector]

That should put out 240hp nominally.

[@g.h.1726]

why don't you soak the lifters in oil like I have seen in other videos

[@JacobVillemain]

It’s not necessary. All modern lifters are pressure checked during manufacturing and are already full of oil.

[@caseycink3268]

Want to rebuild another??!

[@filitamayo]

☹ no break in video.
