+Fireship1 Thanks for watching, it's been a good boat for us. Always fries up. This was the conclusion of the first season we actually had it out for about 10 years. . . But everything ran great the whole season.
Thanks! Yeah, I originally thought this was a GM motor, but you are right, turns out it is a Ford. Oh well. It has been good to me and always fires right up. Thanks for watching!
I could not see the alternator, amazing; have the same boat ,here in poor Portugal, (where the INjustice system,judges,courts,...suck!!) but with a Iveco 8140 Di 2.5 Diesel,turbo, all gone over, from the crank up,factory mechanical pump 11 mm plunger, no kind of electronics,no points,ECUs,nothing, intercooled,around 150 horses; installed it myself,sold my Merc (and drive) to a customer, took both of his in for rebuild; 40 mph, 24 P, very economical but a bit noisy (the original L4 Mercs 140 are also noisy, (also, older boats had poor insulation),i repair them often for customers).
Our boat was a 1971/2 Grew. 17.5 feet with an inline 6 250CI GM/Chev engine (not sure who ultimately made it, i'm sure you know the engine I'm referring to) The engine ran so well. Miss the sound that used to resonate in the hull.
that's not a ford motor it is a mercruiser designed all aluminum engine block that uses a ford 460 head rods and pistons. essentially a half of a 460 ford big block but not really
I do not disagree with you. However, I still label the engine as a Ford since there are more Ford parts than Mercruiser which did not build engines but outdrives. I know the 170 is kind of a strange mix of an engine so it is hard to directly label an engine composed of so many parts. Thank you for your comment.
Very old video and reply. But Mercruiser certainly builds engines. They manufacture their own engines now and for years they built GM crate motors for for GM and the C4 ZR1 Corvette engine was built by them as well.The 3.7L was their own design. They used as many off the shelf parts as they could. Ford was going to buy blocks from them and they were in a Ford Racing catalog in 1988 iirc but it never happened
Biggest thing is make sure the water pump impeller is changed every 3-5 years. Also, check the lower unit gear oil for water. IF you live in a place where water will freeze during the winter, be sure to drain the heat exchanger. Hope that helps. It is a great boat as long as it is taken care of.
One question sir, I have a similar boat 1986 Sea Ray Seville with the 3.0 mercruiser. My problem is the “throttle only” button was broken off and trashed by a previous owner, which makes cold starts difficult (often times I have to disengage the throttle cable and rev the engine manually with the cover off) to keep the engine running when it is cold. Do you know the name of the controller your boat has, I’ve searched a lot online I think it might be like a Quicksilver 3000? I can’t find out for sure, mine looks exactly like yours. Looking to order a replacement, thanks.
Just so you know if you're to the point where you have water freezing and ice all over your boat and also your hose is frozen you are waiting too long to winterize that boat if water can freeze outside it can freeze in the block and crack it start winterizing it sooner
I am not exactly sure. I have never had the boat out long enough to see how much fuel it uses. I do know that it burns 1/4 of a tank on the gauge after 2, 15 minute runs at 3/4 throttle, and trolling all day at idle. It does sip the fuel unlike a v8 engine. Thanks for watching.
That seems like your boat uses a lot of fuel per hour. Although I have never had my boat running for that long at one time so I don't know exactly if that is normal.
Thanks. I believe this boat has really low hours. I know the original owner kept it at a marina stored in a building. Then my cousin bought it, and took it out maybe once or twice a year. And we have been doing the same. Have you changed the points and condenser on your boat? If those points and condenser are old that will really cause the motor to run rough.
The points were totally shot, I switched out to a solid-state sparking system and redid the timing this spring. It sounds better than it did, but still kind of rough and tumble.
That good old 3.7 liter is one of the most reliable and fuel efficient marine engines ever built. Stands to reason it's half of a Ford 460. One of the most bullet proof engines ever made. I don't hold anything against the GM engines or the 454. Why is it so unfortunate it's built off of such a solid platform? You Chevy vs FORD blah blah blah guys are dumb. Back then there wasn't a bad marine engine built really. Today's engines are garbage in comparison. I don't care who makes it. Except the GM 4.3 liter. Reliable yes, powerful yes but mostly on the top end, but a gas hog! Nothin yanked you outta the water like that 3.7 liter four banger other than the V8's. Except the 3.7 used a fraction of the fuel.
That's a fair question. It primes the carburetor with fuel so the engine will start. Otherwise, fuel will not reach the carburetor quickly without a lot of engine cranking.
Have the same boat. 1985 with the merc 140. Still looks good and runs like a top. Nice vid, thanks for posting.

I love that anyone can go boating, even with a Ford Pinto motor. Good for for you bro!!! Keep having fun!
Thanks! Yeah, I originally thought this was a GM motor, but you are right, turns out it is a Ford. Oh well. It has been good to me and always fires right up. Thanks for watching!
It's not a pinto motor. They use the 2.3 overhead cam motor. this is a half of a 460 big block. They only put them in boats.
It's a Mercruiser aluminum engine with a Ford 460 cast iron head.
Pinto motor would make and hold more power then the 5.0
All Ford 460 internals, hardly a Pinto engine! 170-190 hp out of a 4 banger is quite impressive 3.7 liter is bigger than a lot of older V6's
I could not see the alternator, amazing;

Cool I like the cold start videos
+Jason Cruz Glad to hear! This one is a bit different. Since I only have the 3 cars I wanted to do something unique. Thanks for watching.

Mercruiser block and bottom end. 460 ford head. Very good motor.

Welcome to the Future. I have this boat. Any tips?
Biggest thing is make sure the water pump impeller is changed every 3-5 years. Also, check the lower unit gear oil for water. IF you live in a place where water will freeze during the winter, be sure to drain the heat exchanger. Hope that helps. It is a great boat as long as it is taken care of.
What is your idle rpm set to? Mercruiser is a new platform for me since I was dealing with OMC until last year when I picked up a 165 3.7
I just bought a ‘83 Mark Twain it’s got a GM 305 Mercruiser...is it bad that I don’t pump it am I hurting the engine?
You aren't hurting the engine. Pumping it primes the carburetor and makes the engine start quicker.

It's called a Quicksilver "Commander Panel Trim Control" (not the Commander Single Lever Console Control) as per OEM manual
Just so you know if you're to the point where you have water freezing and ice all over your boat and also your hose is frozen you are waiting too long to winterize that boat if water can freeze outside it can freeze in the block and crack it start winterizing it sooner
This boat has closed cooling - winterizing (as far as draining out water that may freeze) entails only draining out the heat exchanger
Are you gonna check the impeller?
I did in the spring and replaced it. Unfortunately, since the filming of this video, it needs to be done again. But it's not too bad to do yourself.
How many eating fuel/h this engine ??
I am not exactly sure. I have never had the boat out long enough to see how much fuel it uses. I do know that it burns 1/4 of a tank on the gauge after 2, 15 minute runs at 3/4 throttle, and trolling all day at idle. It does sip the fuel unlike a v8 engine. Thanks for watching.

My boat 6.2m reagal sebring 1.5 tonn, and 1h ,40liter(10-11 gall) full trottle 54km/h speed...not too much???...maybe carb problem???
That seems like your boat uses a lot of fuel per hour. Although I have never had my boat running for that long at one time so I don't know exactly if that is normal.
my 170 doesn't sound that good even after I took a timing light and smoothed it out as best I could, damn

Mercruiser design and built block and ford head
Yep. I have found this out in recent years. Thanks for watching.

This might be a stupid question but why do you pump the handle?
That's a fair question. It primes the carburetor with fuel so the engine will start. Otherwise, fuel will not reach the carburetor quickly without a lot of engine cranking.
Prime the carburetor. Boats ran carburetors until mid 00s and needed to be primed. Fuel injection is ready to ignite
@@delmontindustriesltd7501 great point. Detrimental to the battery if you don't quickly get ignition
Former boat owners, Bill Gates, Roman Abramovich
Good thing isnt a dodge ir chevy motor would of caught fire exploded and sank boat long ago
I don't know about that. I think the Chevy motor might be a bit more reliable.
