Mean little 4 cyl.

Postby rowdy1 » Sun Dec 25, 2016 10:01 pm

If a man wanted to build a bad ass little 4 cylinder, what combination could you come up? Is it just a stock wide deck o360, or some Frankenstein Cont. with GITSO cylinders? Not a race motor, something that could be reliable.

there's nothing wrong with a 0-360 lycoming or a Continental 0-346 if your one of them type of guys who needs "name brand" stuff, but it's hard to beat the bang for the buck of a Continental pe-90 with 520 angle valve or gitso conversion

To be pushed or towed in by that Lycoming 0-360.

Why don't you just move up to a 450 HP Ecotec? :stirpot:

Is there such a thing as a 250hp 4 cyl. or is that high compression race motor race motor only? Im thinking about building a lightweight deck-over ride boat that would go like stink. I already own a 13x7.5 rivermaster with a 520. I have it set up to go like a tractor for fishing the flats, now I want a something a little "sporty".

You may want to talk to Jr. Jurnigan about a certain Lycoming cam for the 360 series he sells, when he can find them. They go for about $1000 the last I knew. Add a set of 10:1 pistons and the engine should develop somewhere close to 220/225 hp at 2900/3000 rpm.

I may be wrong but I think the cam is originally for the TO-360-F1A6D or the TO-360-C1A6D. According to Lycoming both of these engines develop 210 hp @2575 rpm and 7.30:1 compression.

A four into one exhaust system set up correctly (according to the builders) should add another eight to ten HP. Norman Clay is a good one to talk to about this. I think the set up is somewhere around $1200 to $1600.

As to reliability, any time you stress an engine past it's designed limits...sh!t can happen.

I'll soon find out. I've got the cam and the and the pistons in a rebuilt O-360 on a Jimmy White square nose hull. Just never got around to having the exhaust system built.

[quote="glades cat"]Get some O-541 cyls on a 4 cyl case with high comp Pistons.[/quote] I have seen a couple of boats with 541 lycoming cylinders. I want to say one was on a Lycoming case with cylinders upside down, and one on a continental case. Been awhile.

Why.....bore and stroke appear to be the same as O-360/O-540 series with the exception that they appear to be upstack and for a turbo type engine. From What I can find the "1" on the TIO/TO 541 indicates an integral accessory drive not a HP increase

Well, the ecoturd sure fits the "mean little four banger" requirement. I mean, it is a tiny 122 cubic inch engine.... :shock:

pirate the 541 cylinders are a completely different animal. they are same bore and stroke but the flange location is different on the 541 it moves the cylinder head closer to the block creating more compression. however they are not just a bolt on and go. they have to be modified to work right. whe done you can make big power with big compression and the heads are fairly tough.

No ECO Tecs for me. I have an obnoxious 3 rotor, turbo charged Mazda I would rig up before I did that. The problem is it makes power at 13,000 rpms so I need a 5/1 gearbox. Maybe I'm to old, but the sound of the young idiots with 4 inch exhaust on 4 cylinder rice burners makes me sick to my stomach plus I don't like to wear my pants with my drawers showing!

AMEN.

I have supercharged Honda engine that would be neat on a little sled, but with the time, effort, and money involved to pull that off, I could build a bigger, much more serviceable boat with far less grief.

Ecotecs make power from 2000 to 5400+/- and depending on prop you run a 2:1 up to a 2.6:1 pending prop/HP matchup and match it with a good muffler all you hear is prop tip noise. More power to ya, but build up a good A/C motor an you'll spend about the same if not more cash and burn twice the gas.

I keep telling my grandkids when they get grown enough to have their own, I'm going back to a little 4 cyl. boat.

I'd like a straight valve 180 on lite, single seat rigging. Something that'll run on pump gas if need be & lite enough that I can unstick it by myself as required lol.

Rick I am thinking same as you for my kids in a couple years. Something small and light for sure.

Bigger problem is, how to get multiple boats behind one truck! I can see getting two boats on a long trailer potentially.

Can't say I've seen a rig like in my area yet Russ, but it don't sound completely impossible.

You can put a ball on the back of the front trailer and tow tandem. Launch first boat, the unhook back trailer and launch second. Just have to take wide turns and make sure its legal in the state you are in

Its actually legal for out of state drivers, or out of state vehicles, just not for vehicles registered in Florida.
