Anyone running the HD Mini 35 or the BD 4500? I'm going back and forth between these two motors for a 1754 hull. Any advice or opinions would be great. Thanks.

If you can afford the BD 4500, don't even consider the Mini 35 because the engines aren't in the same league power wise. You will go faster and carry a lot a lot better with the 4500. I have a BD 5500 on a 1750 Gator Trax and if I had to do it again I'd go with the 4500. Just for reference, my boat does 31 with me in it by myself, 28-29 with two guys and a hunting load. With a stock 35hp I'd be at 22-23 mph.

The Mini 35 has the non-cdi motor, so there are a lot more mods readily available for it. Add carb, exhaust & head work, & that 35 mini is a bad lil motor. Not knockin the BD4500, by ANY means, it's a tough motor also, but with the rev limiter built into the coils, ya might as well leave it stock (well, as stock as it is, anyhow). If I were you, I'd contact Deadbird8 about it. He's got ALOT of 1st hand experience with the 2 different engines.

On a different note, aside from the power plant, the Mini is much better than the Sport in my opinion.

Camo, would the sport with a 32" drive do just as good?

I've heard about several guys doin that, & it seems to be gettin popular. I'll be able to tell ya for sure one way or the other in a couple weeks. ;)

Thanks for the info so far guys, this is very helpful. I will be sure to send DB8 a message as well.

Might also ask on the MB forum as well.

Welcome aboard.
If you are thinking of the Mini I would ask MB if you can get the Mini with a CDI Motor.
Give you best of both worlds.

I also answered on your other post. What you are comparing between those two choices are the frame models and standard options in the package. The Sport frame is more weighted back Mini frame is more balanced. I find the Sport frame eaiser to operate, I prefer the way it turns - just my personal preference for my boat and where I run. They only offer the Thompson trim unit (older model) on the Mini frame, and the Sport has the Mercury trim unit which is stronger and provides more range/reach. All this is independent of the power plant, performance options, belt housing size (short/tall - the standard LA special is short transom just like the Sport) and outdrive length you put on it. Its really worth you demoing both if you can before you decide between the two. It will come down to preference and what works well on your boat.

I would recommend you get with a local dealer that is familiar with the areas you run and they can tell you what options work best for the people who have purchased models in the conditions you run. Its normally a good rule of thumb to buy the most power you can afford in the motor. The specific boat (not just the size) is another important piece of information when deciding the options you want/need.

As I stated in my other post you can specify the options you want when you order your motor:

-Mini or HD Sport frame: you can specify either when you order your motor. A more balanced frame requires less downward pressure on the tiller to lift the prop out of the water. The two models handle a little differently but it comes down to personal preference. The sport comes with the Mercury trim unit.

-Short or Tall transom belt housing- this is specified to match the height of the transom on your boat.

-32" drive: you can get on the HD Sport frame, it just comes standard on that 'LA special' model. It seems to do well in the soupy South Louisiana mud where you need more reach to dig out, and on the heavier boats like a GT Gatorhide for example. Its just a longer outdrive option that works better on some hulls vs. others and is useful in some running conditions vs. others.

-CDI or Briggs Marine grade motor: you can get on either frame as an option. The main differences with a regular 35 Briggs is: Stainless stock muffler (more robust than the stock muffler), 50A charging system vs 20A for stock, better wiring harness, lighter flywheel, and CDI coils which have electronic timing advance and 4300 rev limiter built into them. This gives you a little more power out of the crate vs. a stock 35 and idles much smoother at lower RPM. The larger stator will run more accessories and provides charge at idle vs. the 20A stator. There are not 'more mods' available for the non-CDI motor, they are the same, but you have a 4300 Rev Limit in the coils so you have to compensate the performance additions with other things like gear ratio/prop pitch get the most out of the mods. I find that the CDI motor run smoother at lower RPM with either carb. Choice depends on what you plan to do long term on modifications.

-Black Death package of performance options: This is a package of performance upgrades to your base motor purchase. I believe the 'BD package' is mated with the CDI base motor only, however, you can add any or all of the items of the package to a base motor. Its just more economical if you purchase the package vs. buying individual parts/options.
Mikuni performance carb/s- better accelleration, top end, and more precise tuning ability. You can get the single HSR42 w/ BD4500 or dual carbs w/ BD5500. The stock governor/linkage is removed and locked out On a stock motor the carb kit comes with an external electrically controlled rev limiter.
Billeted Throttle Lever- Brake lever style stainless throttle lever on the tiller handle. Some find this more comfortable than the stock one.
IM heads - which are decked for more compression, have larger stainless one piece valves for better flow/performance and robustness (on the valves); the valve springs are shimmed so you can run higher RPM than stock without encountering valve float. You can add the heads to either motor to get the power gains- especially load carrying performance.
Roller Rockers- are recommended with the IM heads which operate the valves, have a higher lift ratio (1.5 vs ~1.32 for the stock stamped steel rocker arms) and give a little better performance.
Billet Push Rods- are recommended with the IM heads. These are stiffer/beefier push rods for operating the valves as the cam rotates.
Gear Ratio- The BD model has a different gear ratio (different top/lower gear size) than the standard Sport or LA Special. The different ratio turns the prop faster at lower RPM but requires more power to perform well. With the 4300 Rev limit and BD performance package, you have the power and gear ratio is used to compensate and keep you under the rev limit.

High Flow Stainless Exhuast Option- As an option, you can upgrade the stock muffler with either the, BPS 'Q' Muffler, BPS crossover or BPS Dual mufflers. All three provide better performance and compliment the other performance mods to allow the motor to breathe better (an integral part of the engine performance improvements is more air in and more air out). The 'Q' is quieter and has better flow than Stock but a little less than the other two (its a trade off of sound vs. max performance). On the noise scale the mufflers go from quiter to louder: Stock muffler, Q- muffler (noise level is very close to stock but with better flow), BPS crossover (with removable silencer), BPS Duals (which have their own 'cool' factor and lower profile). Each of these mufflers produces a different sound and some prefer one over the others, again its personal preference.

Hope this helps sort it out.

Deadbird 8 thank you very much for taking the time to answer my question so in depth. This definitely helps.

ive ran both styles a 26 standard and now a LA special with the 32 " outdrive
and i say i prefer the 32 due to the simple fact that you can get deeper in da mud especially running a heavy load and large boat .way better performance

Post subject:  Re: Mud Buddy Question

The standard is 27" which I prefer in the stumps. Just depends on where you run. SETX performance had some 40" drives made for them if you really need more reach.

Post subject:  Re: Mud Buddy Question

If I were you i would go with the 5500. its one of the most reliable mod motors mud buddy offers, and isint even 1mph slower than the hd7000.. that with a 32, or even a 40" drive would be almost unstoppable
