1968 Barrelback 18 in Belgium : V-drive help

[Morgan's Cloud]

Great pics CB !
Let's see if I can help move things back in the right direction. (Sort of )
What's the latest on that pretty powder blue St Tropez ?

On some inboards the running gear also has to match the motor rotation. You need to determine that the rudder and strut are symmetrical. There is also a rudder alignment issue that will most likely need addressing. Generally it takes more rudder movement to turn the boat against the prop rotation, so the rudder is not equal in movement side to side. At least that is,how it is on my Tunnel Drive Also Note that a 71c/ 1017 is only rated for 310HP @ 4200 RPM you'll need a 72c / 1018 if your going to pump up the HP @ that RPM over that.

Everything seems quite symetrical.
Strut and rudder are the very standard ones found on every early v-drive Donzis

There is no intention now for going up to 300 hp but it is it good to know !

MC thank for asking. I posted the news on the St T post.


Isn't it the early Bertram 31 racer we looked for ?

donzi 18 hull number 208 was not a v drive and not light blue not sure where you are getting those numbers from, look again it may be hull 203

most of the hm v drive motors were standard automobile rotation motors

[Cracker box]

Yes indeed, it is hull 203, (bad memory).
No engine anymore but we still have a bell housing mated to the velvet drive and it says :
Mercruiser 255R ( so Ford 351 clockwise running as i can find) probably not original ? Mercruiser 255´s seems to begin in 1971...
There are numbers on the Donzi boat plate ("EWL 4769" on the attached pic) that I don't understand. Does it refer to a HM engine ?

velvet drive is "As1-71C" clockwise running
V drive is a Crusader
Propeller is a right hand so it runs clockwise in forward when seen from the back of the boat.

Matty, you seems to have access to the great production list.
Was the #203 hull originaly rigged with hollman moody engine ?
what infos do you have ? I'm really interested.

have you got any informations about my light blue St Tropez which had a factory installed volvo AQ110 mated to a AQ110/200 drive probably pre-1966.
It was imported to england first i think. I noticed that Staffan Berg's St Tropez (also in europe) was also factory gelcoated in light blue.
maybe there was once an order for multiple blue boats for europe ? Can you see something in the records ?

[mattyboy]

not a lot of info on that card but the engine was a 210 interceptor which would match that engine serial number a ford 289 started late dec of 67 and sold july of 68

on the St T if you have any serial numbers or more info would help a lot of holes in the early records

[Cracker box]

Cool. That is interesting to know. Thank you.

For the St tropez, I never found any hull number. But I don't really know where to look in particular. I've just re-checked the centerconsole with a purple lamp : nothing there.

[mattyboy]

any numbers on bell housing, drive light blue the original color?

engine : 4 cyl. volvo AQ110/200
4968 07 17314 818
(the underlined number is the serial number)

drive : Volvo AQ110/200 available in Usa from 1964 to 1966 as I once read here.
part number : 2977 923
Serial number : PZ NR 203 606

Every square inch of interior surface on mine was inspected and worked on (including the entire console underside) and no numbers were found either.

This has always been quite intriguing to me 'cause I know that people are always finding numbers on the early 16s of the same vintage .
Does anyone know if there was a run of 16s in the beginning that did not have any numbers at all ?

[mattyboy]

That is an early serial number for the out drive nothing in the record about the st t. I have seen early 16 and 18 a with no numbers once they started with all the color options I think they needed to number the tops an bottoms so they didn't put the wrong deck on the wrong hull with the 19 there were no options the st t deck wouldn't fit on a bench seat hull and most of the st t decks were white so in the early days on the 19 you didn't need a number to keep them straight

WOW
Unrecognizable indeed......

[FlatRacer, aka BarrelBack]

Steering position is determined by prop rotation. If your steering is on the port side, as I suspect it is, then the the prop should be a LH (counterclockwise) rotation. Consequently, the engine should turn RH (clockwise) when viewed from behind the boat. To look at it another way, the engine should turn clockwise when viewed from the front of the engine (the balancer end, not the flywheel end) just as it does in a car.
In a V-Drive installation the engines are installed backwards, as compared to a car or a stern drive installation, so as to orient the bell housing, transmission, and driveshaft toward the V-Drive up forward.
From a manufacturing standpoint, it is much more cost effective to simply mount the steering on whichever side of the boat counteracts the propeller torque then to source counter rotating engines. This is why you see port side steering on the Donzis with Volvo outdrives (LHR), and starboard side steering on the later Donzis with Mercruiser outdrives (RHR).
