I have a boat with a GM 181 CID 4 CYL. IL4 engine. Does anyone what car
this type of engine went in? Easier to get auto parts than hunt for
marine parts...
Thanks, Stan

Uhh, 181 cubic inches works out to just under 3 litres. The Chevette had a
1.8 litre engine if memory serves me correctly.

no, that was the 2.8 V6.

if you don't know, just don't guess. sorry, but i don't like spreading lies
or bad leads. it doesn't help and actually hampers progress.

as far as i know, gm has the 2.2 cav engine, 2.4 dohc quad-4 based and 2.3
quad 4. all other l4's were smaller, i think. the 2.4 is about 155 ci? i
don't know of any gm 4 bigger than the 2.4, as 2.4 is pretty big for a
4-banger.

The old Tempest from 61 through 63 offered a "slant 4" which had a
displacement of app[roximately 194.5 cubic inches, which works out to about
3.18 litres. It was half of a Pontiac 389, made with the same tooling. They
offered it with a 1 barrel carburtetor and about an 8 to one compression
ratio, and with a four barrel and about 10.25 to one compression ratio. We
had one in our 62 Tempest convertible.

I know of no other GM 4-cylinder in that size range, but then again I am not
much of an authority on GM engines.

GM also had the Iron Duke, which was 2.5 liters. It was used in the
S-10 Pickups, the Fiero, and several other cars.

What year? The Iron Duke mentioned by another poster was 151 ci.
Pontiac. Maybe just a number misread? They had an oddly-shaped valve
cover, distributor on the passenger-side (car, not boat). Used in
Monzas, Skyhawks, Fieros, Firebirds (don't laugh)... Back in the late
70's-early 80's.

Pull yer head out and learn something here you mollycoddled little
do-gooder...
..THE FIERO HAD A 2.5 as a base engine, the 2.8 didn't even become
available until the second year. <shesh!>
The fiero had the 2.5 Iron Duke that was replaced after a couple
of years with the 2.5 Tech IV..........

i was trying to help by offering information that i did know. i did not
know the 2.5 iron duke was the base fiero engine, but now i obviously do.

although i did guess the 155 ci, it was not far off from the true 146 cid
that is the 2.4 litre twin cam. as mentioned in another post, and this was
the point i was making, a 2.5 is 151 ci. that means that a 181 ci 4-banger
would have to be much bigger.

using a conversion table, you'll find that 181 ci is equal to 2.97 litres
(bigger than that 2.8 fiero v6). i never used any absolutes like "there was
no 4-cylinder bigger than 2.4." i clearly said i did not know of any.
thus, i do not believe i was spreading incorrect information.

and now, to update, i do not know of any 4-cylinder gm bigger than the 2.5,
151 ci iron duke.

'Sorry for getting all huffy. Me thinks the original poster does
have a 151cid onboard, if you look both your keyboard's upper row of

Maybe it's a marine only engine? Co worker has a 4.7L 4 banger in his boat.
It is a ford, but half of a 460 block. Uses regular car heads, but nothing
else interchanges.

I have one of these, it came from a 60's small truck like GM's early
vans. Have not looked at the source for several years but it was from
a "Motors Manual" which covered vehicles in that time period

The Chev 4 cyl 1962 thru 1969 was 153 ci and Pontiac made a 195 ci 4 cyl
from 61 thru 63.

Bob, you are right and I got my engines mixed up. Also have one of those.
Both in boats and sold by Mercruiser. The 470 Mercruiser is a strange
engine and I think a previous poster is correct.

Correct me if I'm way off here. But a 181 cid is approximately 2966 cc.
Don't know what this engine originally came out of, but how many I4 did GM
make in the displacement range of 3L? Also, no one has asked what, if any,
the block casting number is. Seems to me that it would be easier to
determine when the engine was made and what it's original use was.

Just my 2 cents.

We've already determined this is a marine engine, not to be confused with GM
auto L4's. Marine engines are a totally different breed. In many cases these
blocks are machined by GM then shipped to somebody like Mercury Marine,
where they are assembled according to their specs rather than GM Corporate.
Often times, GM produces spares/parts by contract, but does not include them
as part of Service Parts Operations.

Do you want to sell it? It is a special marine variant of the 180ci 2966cc 120/140 hp inline 4cyl the front mount was a screw arrangement for trimming the boat. The rear seal was a one piece type and was designed to run at 4000 to 4400 rpm all day...the closest fit would be a base early model Chevy nova......I need it if you want to sell it..
