Which top mount starter to buy
 
Have no experience with CCW starters/or top mount starters for BBC boat engines, as have narrow stringers and top mount 2-bolt bellhousing so though might as well use it.
Only used tilton CW starters in cars
Need reliable, good cracking starter and if possible to save some weight
What's eveyone running:
1. API marine 10MT delco
2. Delco Remy MT14
3. Delco gear reduction style
4. Denso gear reduction style

#3 worked well on 540's w/ blowers.still going as of today,about 10yrs later.

what you mean might as well use it. do you have top mount starters now? and if so, which ones? if you have bottom mounts and want to switch you need different flywheels or to have ring gear installed on the other side of the flywheel.

brett fiddes 11-05-2017 07:07 AM

Have no starters for the marine engine now
stringers are only 22" wide so its seems a little tight to fit the starter in between
Therefore need to buy new a starter
Have the top mount bellhousing thought I would run them
have a few flywheels here a mixture of alum and steel auto and marine, although haven't paid to much attention to whether they would ift
So need to change the ring gear on flywheel
can you run a flex plate with this setup and use a spacer as saw Rex marine has 1/2" spacer plate which looks like it may do same job
Big Block Chevy Flywheel Spacer, 1/2" thickfor use with Flexplate and Reverse Rotation Starters: Automotive Performance Products, Boat & Marine Parts & Hardware

Thanks for the infor. actually setting up engine/transmission/drive mounting plates in boat so just trying to think ahead
cheers

You can tell by looking at the flywheel if the ring gear is mounted toward the front or rear. I had a machine shop change mine. I found that not all machine shops could do it.

You can change the ring gear with a propane torch, a 2 2x4 blocks, a punch and a hammer.
Set the flywheel on the 2x4 blocks, heat up the ring gear and lightly tap around the gear and it will fall off.
Make sure you grind off the spot welds if someone spotted it to the flywheel.
I've done it about a dozen times

If i remember correctly my flywheel had a groove machined into it. The ring gear had a slight protrusion on the underside that rode in that groove to ensure it didn't move. This groove needed to be remachined into the correct place place on the flywheel to relocate the ring gear. Not all machine shops had a lathe that could accommodate the flywheel. Thats my story and im sticking to it. As far as what brand starter, I found a local shop that rebuilt starters with quality parts not the chinese stuff they are filled with when new.

Delco Remy MT14 I do believe these have the most HP

brett fiddes 11-05-2017 06:52 PM

Guys
Thanks for the infor,
I'll need to go through the steel and aluminium flywheels to see what I have and can use
For the starter selection I looked at the weights of the starters and looks like option 1&2 are 23 pounds, and option 3&4 are 10lbs in weight. So I only have small 21' boat so was trying to see whether I could keep the weight down a little. Not sure what the gearing is on the Delco reduction gear starter (#3) but Denso looks to be 3-4/1

As far as flywheels go, do most people normally use the standard nodular iron flywheel, steel or aluminium. The boat is being used for play boat in harbour/open bay, running turbo 502ci or 560ci N/A BBC, through Daytona crash gearbox, casale parallel drive (so can be geared over/or under drive),
I suppose with aluminium when you take your foot out of the gas you lose the rotating inertia, I was planning on running 14" flywheel

any help much appreciated

Your not going to run a shaft whirl away in the boat can be dangerous if your at good speed and something fails. I have run aluminum flywheel in my v-drive with SBC worked great. What boat do you have??

brett fiddes 11-05-2017 08:49 PM

No not running a whirl away
The casale/Hallcraft drop box is fixed drive between crash gearbox (F,N,R) to step up from the Arneson Drive coming through transom.
This boat as far as I can make out is levi designed hull, and previously was offshore ski boat racing in Nth Queensland Australia, with large outboard.
It was then purchased and previous owner who had outboard business, and wanted to convert it to stern drive. I purchased it after it was sitting for 6 yrs, and started to rebuild stringers (which were rotten in rear 6 ft), and replaced transom to suit the surface drive. Basically I started with clean sheet paper, hull up
Im travelling at present in Phils on holiday so tried to get into my google pictures, but locked out, might have to wait until I get home end of week. Here is the boat as picked up, and in Jan/17 lifted it on to dolly to do the surgery.
I put first flocote on floors and front part of deck. As need to make engine mounts, and then can finish the glass the floor over inner stringer, and seal up finish flocote
The plan is too throw it in the drink over christmas break and see if any holes/leaks, then finish the engineering side, figure out where to put fuel tanks, and seats ( a little short on room for rear seat), nothing standard in this boat, so need some intelligent suggestions
Ill update the pics in weekend
cheers Brett

hopefully this will work

I need to update the photos on the google pics, next week

dereknkathy 11-07-2017 12:03 PM

I don't know, dude. I think it'll be a little underpowered. actually about 30 years ago, this car parts store across from where I worked had a 21 with either an arnie or kaama drive. they said it had a tendency to try to push the nose down into the water at 70 mph or so.

brett fiddes 11-08-2017 06:40 AM

Derek
yes I had heard this
however when I read the Arneson Tech data on how to setup transom
i was sure to follow correctly
the Arneson is Trimable andvif needed I have a pair of
19” k-planes if they are needed
the front of engine is approx sitting at < 22% of the length
i just need right think about where to place the fuel tanks
as was hoping to run at least 50 gallons
