1996 150 fast Strike Mods?.............any OMC HP seekers?

[285king]

I know some other crazy person has thought about decking heads on one of these. Just wondering if anyone knows the factory cc of the chamber or how much you could take off?

[hulapopr]

i don't know but go on bass and walleye boats mag,they did a hop up of the eagle series at monty racing in fla. and it was strong.if you go back and read it it has all the specs on it.

You need to consider that option carefully. It requires the use of 89 octane minimum, and with gas where it is, I am not sure its a good idea. You also put yourself at risk of getting detonation knock, which is a common problem with these engines when you raise compression, and it will kill it in short order.

A better one is to find a set of Ficht 150/175 reed cages and use them in place of what is in there. I am going to do that mod soon with my engine, and use boyesens as well.

I can tell you from looking at the reed blocks from the FFI engine, they should flow more.

Sam Baker is working on retooling their hot heads for these engines, which are worth about 12 hp over stock, and do not require higher octane fuel. That is the route I am going.

[Lockjaw]

Oh and one other thing. Do not even think about cutting your heads without some "expert" advice. If you screw up the squish, which you will if you mill them, you will have a boat anchor for an engine in very short order.

If you want cut heads, get them from Monty Racing. He will send you the heads, gaskets and proper jets for the carbs. You will have to run at least 89 octane.

Or you could wait on Sam Baker to retool the hot heads, and get the HP monty does, without having to run higher octane.

If you want to port it, I know someone who can do that and perk it up a little bit.

I would really like to put a 175 PH on mine. Then run Ficht cages with boyesens, and have Monty do the tuner mod. Its worth 6 hp.

[285king]

Thanks for the info, e-mailed Monty yesterday on this subject. Keeo me posted on yours. What years should I ask for for the reed cages on the FICHT?

[hulapopr]

not trying to be a smarty pants but your only looking at .10 a more for a gallon of 89 oct,$4.00 for 40 gallon if you can afford the hop up the gas will be no problem..
is you boat only rated for a 150?just curious as it may be more worthy to buy a complete 200 or 225 and replace the 150..

[285king]

I have considered the "Black engine" route but controls, oil tank, tach etc. also. 200 OMC is out of the question, I know how they hold up This 150 is VERY strong fo rits age, I have been told that as far as 150's go this was the best performer to date. Maybe if I would spring for a 175 Pro XS Boat is rated for a 175

[Lockjaw]

97 or 98 out of a 150 or 175. YOu will need Boyesen Reeds part number B164P.

[Lockjaw]

Oh and Monty can port it and get a good solid 200 hp out of it, One of the guys on Fastbass got 202 out of his from Monty.

Its way cheaper then a new engine. Plus its funny to spank someone with a big engine when you have a little one.

[Wookie]

What all mods and $$$ did it take to get 200+ out of a 150? What did it do for the longevity of the motor?

[hulapopr]

if you read the aricle it tells you in depth,porting,heads carbs,exhaust mods.It isn't much more than a stock rebuild for what you get.longevity should be good because they still run the same rpm you just have enough power to turn a bigger prop.

speed cost money how fast do you want to go???

[Lockjaw]

I would expect somewhere around 3500 for the whole deal, more if you need to replace pistons. The best thing to do is take your boat to him, so he can dyno it before and after.

That also is the best insurance against detonation knock too.

You could also have it ported and not raise the compression, and have him do the tuner mod to it, that is worth 6 hp by itself.

Oh and just so you know, Tony Brucato, who makes lots of stuff for Mercury's recently came out with efi for the big loopers. He will eventually come out with it for these engines too. I asked him, he said it was on the agenda.

What I think you will see in the next couple years is alot more support for making modifications to these engines because alot of people cannot afford to pony up 12k for a new motor, or they don't want to have a 4 stroke. I know I don't want a 4 stroke, except I do like the Suzuki's.

[285king]

Thanks man, Im going to try Montys again in morning if I dont go to the lake. Tried once but got recorder.

I looked for Bakers website but had no luck...

[Lockjaw]

He is working on finding a machinist. I ran him down on Scream and Fly, and emailed him over the weekend.

I also know another guy on S&F that has ported one, put the ficht cages and reeds in it, and he says it pulls a prop he could only spin to about 5200 to 6100 now. Says his boat is running around 76 gps.

He didn't raise the compression, so that seems to eliminate the issue of detonation knock. I can try to put you in touch with him if you like. He's a nice guy, did me major right on my FS carbs I got from him.

Man if my little boat would run 76, I could have some fun around here making money.

[Lockjaw]

Look I should have boyesens for mine in a few weeks, and then I will put the cages in and see what happens. I am up to the top on my jack, which is either 3 inches below, or 2.75 inches below the pad. Not sure what I am going to do next.

I have the motor all the way up too. Have plenty of H20 pressure, and I am running a TR04 25p prop. Turning it about 5200 according to my tach. GPS is 63.3 with a load a partner. If I can get another 100 rpms out of the reeds and cages, I bet light with just me I will get real close to 70.

[hulapopr]

did you see the cost of that f.i system for the loopers??you can buy alot of gas or sell the looper and put the efi money with it and buy a newer d.i motor...<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Lockjaw &raquo;</TD></TR><TR><TD CLASS="quote">I would expect somewhere around 3500 for the whole deal, more if you need to replace pistons.

You are right, its expensive, and not for everyone, however it is tuneable for a modified motor. Try and modify a DI Johnnyrude and see what happens to it.

So in cases where you have a HP limit of 150 or 175, your choice is to buy a new DI in that range, or buy a FS 150/175, port it and put efi on it, and have 200ish HP.

In my case, I am limited to 150 hp engine, I can't go to the dealer and tell them to hang a 200 Etec small block on my boat, they won't do it.

So in this case, I would probably be looking at 7.5k to rebuild and port my engine, and add the EFI. That is much cheaper then paying 12k for a new DI engine, and mine would be more powerful.

If stock works for you, fine, for me, I like to have a little more then stock, which is why I bought headers to put on my tundra, have a k&n FIPK, and dynomax exhaust.

That is true, but for me its sorta like what do you like better. A 69 Camaro SS with a big cam hot rod motor, or a new Camaro...
I myself like to tinker with stuff and make it better. Adding EFI to a older motor IMHO would make it much more reliable and fuel effecient. If I can get my 60 deg V4 to crank like the factory EFI motors do I will keep it till the thing falls apart.
